To find out how many months Simba will take to repay the loan, we need to calculate how many 2-week periods are in a month. Since there are 52 weeks in a year, and 12 months in a year, there are 52/12 = <52 2="4.33">>4.33 2-week periods in a month.
Simba returns 4.5% of the loan amount, which is $12,000 x 4.5/100 = $<12000*4.5 00="540">>540 every 2 weeks.
Therefore, Simba repays $540 x 4.33 = $<540*4.33=2338.2>>2338.2 every month.
To find out how many months Simba will take to repay the loan, we divide the loan amount by the monthly payment: $12,000 / $2338.2 = 5.13 months.
Therefore, Simba will take approximately 5.13 months to repay the loan. Answer: \boxed{5}.

Since we have an average rate question we can use the following formula:
average rate = total distance / total time
Since the distance is the same in both directions, we can use a smart number to represent the one-way distance. A good number to use would be one that is divisible by both 5 and 12, so we can let the distance each way = 60.
So, the time going to work is 60/5 = 12, and the time going home from work is 60/12 = 5.
Finally we can determine the average rate:
average rate = total distance / total time
average rate = (60 + 60)/(12 + 5)
average rate = 120/17

The best answer is E.
The original equation is a3 +8a2 – 20a, it can be written as a(a – 2)(X + 10). The roots are 2,0 and (-10).
We are looking for an equation that has none of the same roots.
Answer E: X2 – 10X +16 = (X + 2)(X + 8) à This equation has none of the original roots. All the other answers have one or more of the same original roots.

Understanding the given information:
Robin earns 30% more than Erica.
Charles earns 60% more than Erica.
Calculating the wages:
Let's assume Erica earns $100.
Robin earns 30% more than Erica, so Robin's earnings are $100 + 30% of $100 = $130.
Charles earns 60% more than Erica, so Charles's earnings are $100 + 60% of $100 = $160.
Calculating the percentage difference:
Now, we need to find out how much % the wages earned by Charles is more than that earned by Robin.
The difference in their wages is $160 - $130 = $30.
To find the percentage difference, we divide the difference by Robin's earnings and then multiply by 100.
Percentage difference = ($30 / $130) * 100 ≈ 23%
Therefore, the wages earned by Charles is approximately 23% more than that earned by Robin. Hence, the correct answer is option (a) 23%.
Robin earns 30% more than Erica.
Charles earns 60% more than Erica.
Calculating the wages:
Let's assume Erica earns $100.
Robin earns 30% more than Erica, so Robin's earnings are $100 + 30% of $100 = $130.
Charles earns 60% more than Erica, so Charles's earnings are $100 + 60% of $100 = $160.
Calculating the percentage difference:
Now, we need to find out how much % the wages earned by Charles is more than that earned by Robin.
The difference in their wages is $160 - $130 = $30.
To find the percentage difference, we divide the difference by Robin's earnings and then multiply by 100.
Percentage difference = ($30 / $130) * 100 ≈ 23%
Therefore, the wages earned by Charles is approximately 23% more than that earned by Robin. Hence, the correct answer is option (a) 23%.

Nikhil Khanna answered |
To determine if a given equation has the root P, we can substitute P into the equation and see if it equals zero.
Substituting P into the equation X^3 + 10X^2 + 16X:
P^3 + 10P^2 + 16P = 0
a) X^2 + 10X + 16:
Substituting P into this equation:
P^2 + 10P + 16 = P(P + 10) + 16
Since P(P + 10) + 16 = 0 (from the original equation), this equation also has the root P.
Therefore, the answer is a) X^2 + 10X + 16.
Substituting P into the equation X^3 + 10X^2 + 16X:
P^3 + 10P^2 + 16P = 0
a) X^2 + 10X + 16:
Substituting P into this equation:
P^2 + 10P + 16 = P(P + 10) + 16
Since P(P + 10) + 16 = 0 (from the original equation), this equation also has the root P.
Therefore, the answer is a) X^2 + 10X + 16.

The best answer is B.
Every three months Rusty gives the bank $40,000.
After the first quarter the bank took (0.0025 x 1040000 = 2600) and Rusty paid $40,000 so the new Debt is now (1,040,000 - 40,000 + 2,600 = 1,002,600).
After the second quarter the bank took (0.0025 x 1002600 = 2506.5) and Rusty paid again $40,000 so the new Debt is now (1,002,600 – 40,000 + 2506.5 < 1 million dollars).
After the first quarter the bank took (0.0025 x 1040000 = 2600) and Rusty paid $40,000 so the new Debt is now (1,040,000 - 40,000 + 2,600 = 1,002,600).
After the second quarter the bank took (0.0025 x 1002600 = 2506.5) and Rusty paid again $40,000 so the new Debt is now (1,002,600 – 40,000 + 2506.5 < 1 million dollars).

Did all three bids arrive on time last night? We need to minimize delays on construction, so if the contractors have submitted their estimates and our research team has compiled reports on the contractors’ histories, we should make a decision on which firm to hire by the end of the day.Email #2
Email from financial officer in response to the project manager’s August 3, 9:43 a.m. email
August 3, 10:12 a.m.
Appaloosa Construction sent us a bid of $1.35 million. Its bid is the highest of the three, but its track record is spotless; none of the past 10 major projects it has worked on has gone over budget by more than 4 percent. Breton Construction did manage to underbid them—its representative claims that it can do the project for $1.25 million. However, in the past two years, Breton oversaw two different projects that went over budget by a full 25 percent. If our project were to exceed Breton’s estimate by a comparable percentage, we would run out of funds before completion. Finally, Campolina Construction presented a $1.1 million plan, and its track record is as good as Appaloosa’s. Unfortunately, although Appaloosa and Breton can both start tomorrow, Campolina would be unable to begin work until August 25, so we cannot accept Campolina’s low bid.Email #3

Even though Breton’s work could potentially cost less than either of the other two, that savings does not justify the risk of being unable to complete the project. But as far as Campolina is concerned, you’re not considering the actual cost of a delay. It’s true that we are losing money at a constant rate each day we don’t start building. But even after factoring in the losses of waiting until August 25, the estimated cost of working with Campolina still ends up $50,000 below Appaloosa’s bid.Consider each of the following statements.

Appaloosa Construction sent us a bid of $1.35 million. Its bid is the highest of the three, but its track record is spotless; none of the past 10 major projects it has worked on has gone over budget by more than 4 percent. Breton Construction did manage to underbid them—its representative claims that it can do the project for $1.25 million. However, in the past two years, Breton oversaw two different projects that went over budget by a full 25 percent. If our project were to exceed Breton’s estimate by a comparable percentage, we would run out of funds before completion. Finally, Campolina Construction presented a $1.1 million plan, and its track record is as good as Appaloosa’s. Unfortunately, although Appaloosa and Breton can both start tomorrow, Campolina would be unable to begin work until August 25, so we cannot accept Campolina’s low bid.

Even though Breton’s work could potentially cost less than either of the other two, that savings does not justify the risk of being unable to complete the project. But as far as Campolina is concerned, you’re not considering the actual cost of a delay. It’s true that we are losing money at a constant rate each day we don’t start building. But even after factoring in the losses of waiting until August 25, the estimated cost of working with Campolina still ends up $50,000 below Appaloosa’s bid.

- In making their decision, the project manager and the financial officer considered how much time the contractors would spend on construction.
Answer: No
Based on the emails, the time contractors would spend on construction is not explicitly mentioned as a key factor in their decision. Therefore, this statement cannot be accurately inferred. - The project manager and the financial officer disagree about the best choice of contractors for completing the project.
Answer: Yes
The emails indicate that there is a disagreement between the project manager and the financial officer about which contractor is the best choice for the project. - The project manager is willing to wait a few days before deciding on Campolina’s bid.
Answer: No
The emails do not mention the project manager being willing to wait a few days before deciding on Campolina’s bid. Therefore, this statement is not supported by the information.
Hence, the correct options are:
In making their decision, the project manager and the financial officer considered how much time the contractors would spend on construction: No
The project manager and the financial officer disagree about the best choice of contractors for completing the project: Yes
The project manager is willing to wait a few days before deciding on Campolina’s bid: No

1. We see that the percentage of Surgeons and even Paramedics wearing protective gear is higher than the veterinarian across all types of gears. This can be explained by "Humans catch diseases from other humans much more easily than from animals." Hence, the first statement "Would Help Explain" the information in the table.
2. We see that a higher percent of Construction Workers wear earplugs or hearing protection compared to Paramedics. This could be explained by "Ambulance sirens are loud, but they don't damage people's hearing as much as power tools do." Hence, the second statement "Would Help Explain" the information in the table.
3. There is no information in the table that can be explained by "About 10% of janitors earn extra pay for cleaning hazardous areas." Hence, the third statement "Would Not Help Explain" the information in the table.

Let number of second shift workers be n
Then number of first shift workers = 2n/3
Let b the number of bulbs made by each worker in the first shift
Then number of bulbs made by each worker in the second shift is 4b/3
Total bulbs made by first shift workers: 2nb/3
Tota bulbs made by second shift workers: 4nb/3
Total bulbs by both: 6nb/3 => 2nb
Now try substituting value of 2nb (first column) to find nb and get 2nb/3 (second column)
If 2nb =3, nb. = 3/2 not possible => eliminate
If 2nb = 6, nb = 3 => 2/3 nb = 2 which is not present => eliminate
If 2nb = 12, nb = 6 => 2/3 nb = 4, again not present => eliminate
If 2nb = 24, nb = 12 => 2/3nb = 8, again not present => eliminate
Therefore only 36 should fit in. Let's check
2nb = 36 => nb = 18 => 2/3nb = 12
Hence Total Bulbs for Both Shifts (Column 1) = 36
Total First-Shift Bulbs (Column 2) = 12
Then number of first shift workers = 2n/3
Let b the number of bulbs made by each worker in the first shift
Then number of bulbs made by each worker in the second shift is 4b/3
Total bulbs made by first shift workers: 2nb/3
Tota bulbs made by second shift workers: 4nb/3
Total bulbs by both: 6nb/3 => 2nb
Now try substituting value of 2nb (first column) to find nb and get 2nb/3 (second column)
If 2nb =3, nb. = 3/2 not possible => eliminate
If 2nb = 6, nb = 3 => 2/3 nb = 2 which is not present => eliminate
If 2nb = 12, nb = 6 => 2/3 nb = 4, again not present => eliminate
If 2nb = 24, nb = 12 => 2/3nb = 8, again not present => eliminate
Therefore only 36 should fit in. Let's check
2nb = 36 => nb = 18 => 2/3nb = 12

The best answer is D.
The original equation is X2 + 3X – 54, it can be written as (X – 6)(X + 9). The roots are 6 and (-9).
We are looking for an equation that has one of the same roots.
Answer D: X2 – 15X +54 = (X – 6)(X – 9) à This equation has the root 6.
All the other answers have different roots than the original equation

We should be wary of the fact that the question asks for combined revenue to combined expense ratio. We must not simply add their R/E ratios. From chart 2, we get their respective R/E values.
We need not calculate combined revenue and combined expense for each of the options. Logically, R/E ratios for C and D lie in bottom two, hence their combined revenue, and combined expense will also be least. So the answer is CD. The table below shows that combined revenue to combined expense ratio for CD will be the lowest. It lies between 1~0.9.

- Approximately 15 percent of 8th graders in 2017 participated in exactly one of the six after-school activities:
- From the graph, the percentage of 8th graders participating in one activity is approximately 15%. This corresponds to Blank 1.
- In 2017, there were two grade levels in which more students participated in sport activities than non-sport activities:
- The two grade levels where more students participated in sports activities (soccer, tennis, or track) than non-sport activities (math team, band, or debate team) are the 7th grade and 12th grade. Hence, Blank 2 is "were two grade levels".
The correct answer is Option C:
Blank 1: 15
Blank 2: were two grade levels

Poisoning from ingesting poisonous plants or mushrooms is a common issue, with particular significance in certain regions. For instance, tropical areas often serve as hotspots due to the prevalence of native poisonous plant species, sometimes used intentionally. In temperate regions, such as Europe and parts of North America, mushroom poisoning frequently results from accidental misidentification during foraging or wild cultivation. Certain types of plant or mushroom poisoning have relatively high fatality rates, particularly in cases of delayed treatment. However, these fatality rates vary by region; in some Western countries, the fatality rate for mushroom poisoning is relatively low.

Poisoning by mushrooms
- A person in a rural area of Europe collecting mushrooms from the wilderness and using them to prepare a salad for his family.
Foraging wild mushrooms poses a high risk of poisoning due to potential misidentification, a common cause of mushroom poisoning in temperate regions.
Poisoning by plants
- A person in an equatorial forest consuming tree bark he personally identified as possibly having hallucinogenic properties during a self-guided tour.
There is a high risk of poisoning because self-identifying and consuming tree bark, especially in an equatorial forest with potentially unfamiliar plant species, is inherently dangerous.
Analysis of other options
- A person in Eastern Asia eating soup that contains rare and exotic vegetables prepared by an experienced chef.
There is a low risk of poisoning because an experienced chef is unlikely to use toxic ingredients, even in a soup containing rare or exotic vegetables.
- A person in Sicily, who is allergic to mushrooms, requesting mushrooms to be removed from a pizza before eating.
There is no risk of poisoning because mushrooms are avoided entirely, making this irrelevant for both mushroom and plant poisoning.
- A person in North America observing the ritual burning of fungi, including a type of mushroom known to be highly toxic.
There is a low risk of poisoning because observing from a distance minimizes exposure to any potentially harmful fumes, making this largely irrelevant for both mushroom and plant poisoning.
Correct answer:
Poisoning by mushrooms "A person in a rural area of Europe collecting mushrooms from the wilderness and using them to prepare a salad for his family."
Poisoning by Plants "A person in an equatorial forest consuming tree bark he personally identified as possibly having hallucinogenic properties during a self-guided tour."

Statement 1: Fifteen of the 16 pieces sold. The eighth highest sale price is the median of the set of sale prices. This price is $1800.
Answer: No
Statement 2: The probability that a piece by Masterson sold for more than $2000 is 33%, but that’s not what the question is asking. Five pieces in total sold for more than $2000, and two of them were by Masterson, so the probability is 2 out of 5, or 40%.
Answer: No
Statement 3: This will take some doing, since there’s no neat way to sort the table in order to get all the canvas and paper works grouped neatly together. It is also not easy to eyeball the table and judge whether paper or canvas works had a higher average sale price so you should calculate the actual averages. Sorting by material helps a little. Six pieces were on canvas. Their average sale price was:

First, let’s define our two variables:
M = Marla’s age today
A = Angelina’s age today
Next, we can write two equations from the information presented in the problem stem.
Since Marla is 20 years older than Angelina, we have:
M = A + 20 (equation 1)
Since in 5 years, Marla will be 3 times as old as Angelina, we have:
M + 5 = 3(A + 5)
M + 5 = 3A + 15
M = 3A + 10 (equation 2)
Next, from equation 1, we can substitute A + 20 for M in equation 2, and then solve for A:
A + 20 = 3A + 10
10 = 2A
5 = A
Finally, we see that Angelina is 5 years old. Thus, Marla is currently 5 + 20 = 25 years old. So, in 3 years, Marla will be 28 years old.

(1) The number of households in the Midwest that do not use electricity for heating = (100-18)% of 25.9 million i.e. 21.238 million.
The number of households in the US that use electricity for heating = 35% of 113.6 million i.e. 39.76 million
Thus,
21.238 million/ 39.76 million = 0.534
That's closer to 1/2
(2) The number of households in the Midwest that use either propane/LPG or natural gas for heating : (69 + 8)% of 25.9 million i.e. 19.943 million.
Thus, the average number of households using either propane/LPG or natural gas for heating per state = 19.943/(total number of states = 12) = 1.66 million
That's closer to 1.7 million.

Breton Construction did manage to underbid them—its representative claims that it can do the project for $1.25 million. However, in the past two years, Breton oversaw two different projects that went over budget by a full 25 percent. If our project were to exceed Breton’s estimate by a comparable percentage, we would run out of funds before completion. Finally, Campolina Construction presented a $1.1 million plan, and its track record is as good as Appaloosa’s.

Even though Breton’s work could potentially cost less than either of the other two, that savings does not justify the risk of being unable to complete the project. But as far as Campolina is concerned, you’re not considering the actual cost of a delay. It’s true that we are losing money at a constant rate each day we don’t start building. But even after factoring in the losses of waiting until August 25, the estimated cost of working with Campolina still ends up $50,000 below Appaloosa’s bid.The amount of money lost each day that construction is delayed is closest to

To determine the correct answer, let's analyze the frequencies of the words in the different sections for each of the pairs mentioned in the options. We will check if the frequencies of the words show a positive correlation, meaning as one increases, the other also increases in the same sections.
Pair 1: Word 1 and Word 3
Let's look at the frequencies for Word 1 and Word 3 across all sections:
As we can see, as the frequency of
Word 1
increases (from Section A to Section C), the frequency of
Word 3
also increases in a similar pattern, indicating a positive correlation. Therefore,
Word 1 and Word 3
are
positively correlated
.
Conclusion
:
Yes
(positive correlation)
Pair 2: Word 2 and Word 5
Let’s examine the frequencies for Word 2 and Word 5 across all sections:
As we observe, the frequencies for
Word 2
and
Word 5
do not follow a clear upward or downward trend together. For example, in Section A, Word 2 has a frequency of 2 and Word 5 has a frequency of 7, but in Section G, Word 2 has a frequency of 12 and Word 5 has a frequency of 1. This shows no consistent positive correlation.
Conclusion
:
No
(no positive correlation)
Pair 3: Word 5 and Word 6
Now, let’s look at the frequencies for Word 5 and Word 6 across all sections:
Here, we can see that as the frequency of Word 5 decreases (from Section A to Section G), the frequency of Word 6 also generally decreases in a similar pattern. This indicates a positive correlation between the two words.
Conclusion: Yes (positive correlation)
Final Answer
- Word 1 and Word 3: Yes (positive correlation)
- Word 2 and Word 5: No (no positive correlation)
- Word 5 and Word 6: Yes (positive correlation)

This question needs classification of stocks, so we first read the relevant data from the charts and classify the stocks.
For Stock Valuation Classification (SV Classification), we read the data from chart 1. The data is given below. We find that stock D cannot be classified per any category of SV Classification.
From Chart 1
For Profit Generation Capability (PGC) classification, we read the data from chart 2.
The percentage of profit is given as (profit/revenue)*100%.
Let’s take stock A first.
R/E ratio for A is 1.3 or 1.3/1. It means that for a revenue of $1.3, expense is $1, and profit is R-E=1.3-1=0.3. So % profit would be (P/R)*100 = (0.3/1.3)*100% =23.08%.
Similarly, for other companies, profit percentages are calculated given below.
From Chart 2
1. a.There is no stock that is not classified for both the categories. In the SV classification, stock D is not classified, whereas in the PGC classification, stock C is not classified. But both these stocks are classified per at least one of the categories, so the answer is NO.
1. b. B stock is Volatile Bear-Struggler. Let’s look at the criterion of Volatile Bull.
Volatile Bull - A stock whose TOP is more than 30% and BOTTOM is less than 10%.
Presently, TOP of stock B is 9% and BOTTOM is -12%. B only qualifies for the BOTTOM criterion of Volatile Bull.
To turn it to Volatile Bull, we need to increase its TOP by more than 30% -9% = 21 percentage points. It is more than 20 percent point increment. So the answer is no. No.
1. c.From the table, we know that A stock is the Rain Maker stock. The revenue of the company of stock A is approximately $230, and R/E ratio is 1.3. This gives expenses as 230/1.3 = $176.92. The value is not approximately $230, hence the answer is No.

I. Assuming that the airline has the option to suspend up to three routes in order to mitigate the financial losses, it would be preferable to suspend the routes with the least passenger revenue. Based on the pie chart, the routes contributing the least to passenger revenue are:
- Regional (2%)
- Far East (5%)
- EU (7%)
These three regions contribute the least to the airline’s passenger revenue, so Blank 1 is: EU, Far East, and Regional.
II. The ratio of the revenue of the most costly route (KSA) to the least costly route (Regional) is calculated as:
- Most costly route: KSA with 28% of revenue.
- Least costly route: Regional with 2% of revenue.
The ratio of the revenue of the most costly route to the least costly route is:
28% / 2% = 14:1
Therefore, Blank 2 is: 1:14.
Thus, the correct solution is:
Option A:
- Blank 1: EU, Far East, and Regional
- Blank 2: 1:14

The best answer is C.
If 1/X is 2.5 or 5/2 then X = 2/5.
1/(2/5 – 2/3) is 1/(6/15 – 10/15) = -15/4 = -3.75.
If 1/X is 2.5 or 5/2 then X = 2/5.
1/(2/5 – 2/3) is 1/(6/15 – 10/15) = -15/4 = -3.75.

The best answer is B.
There are (420 – 312 = 108) girls in Parkway.
86% of 250 are boys, therefore 14% of 250 are girls that play soccer, which is 35 girls.
The number of girls that do not play soccer is (108 – 35 = 73).

Dana takes 5500 each year and returns (0.03 x 5500 = 165) each month, which is (165 x 12 = 1980) each passing year. That means that each year Dana owes her parents (5500 – 1980 = 3520) pounds.
After 4 years in college she will owe them (4 x 3520 = 14,080) pounds.

(1) The species with a greater need to manage the population is the one with low management needs but High capability (population) need. California sea lion fits the category.
(2) The species with a greater need to manage the population, as well as greater management need, is the one with High management needs and capability (population management) need. Ice seal fits the category.
Hawaiian monk seals don't fit the category because it's not on the same population management need level as of California sea lion.

Multiple Sleep Latency Test
The multiple sleep latency test (MSLT) is the most widely used objective assessment procedure for excessive daytime sleepiness. It consists of a series of five nap opportunities given every two hours in a sleep laboratory. The patient lies in a darkened, sound-attenuated room for up to 20 minutes and is instructed to fall asleep. The average latency to sleep onset over all nap opportunities provides an index of sleep propensity.
As a general guideline, only mean sleep latencies shorter than 8 minutes on an MSLT are considered abnormal, and latencies shorter than 5 minutes are taken to indicate severe excessive daytime sleepiness. A patient with a mean sleep latency of 2 minutes or less on an MSLT is unlikely to be exaggerating a complaint of excessive daytime sleepiness, to suffer from fatigue rather than sleepiness, or to be free of any sleep disorder.Patient Data - Ramesh is a 34-year-old man with no major health problems who takes no prescription medicines.
- Sara is a 23-year-old woman with asthma who takes a prescription stimulant daily for treatment.
- Angel is a 72-year-old woman with major depressive disorder who takes a prescription anti-depressant daily.
- John is an 11-year-old child who has been diagnosed with ADD, but does not take any prescription medications.
- Steve is a 54-year-old man with mild heart disease who takes several over-the-counter supplements.
MSLT Results
NOTE: Data given is time until sleep in minutes and seconds. Results may be misleading if they are affected by patient age (different criteria apply for children under 16), noise in the sleep center, patient anxiety during the test, or atypical sleep on the previous night. Use of prescription medications such as stimulants or antidepressants can also lead to misleading results.For the following statements, select True if the statement is inferable from the data provided. Otherwise select False.

As a general guideline, only mean sleep latencies shorter than 8 minutes on an MSLT are considered abnormal, and latencies shorter than 5 minutes are taken to indicate severe excessive daytime sleepiness. A patient with a mean sleep latency of 2 minutes or less on an MSLT is unlikely to be exaggerating a complaint of excessive daytime sleepiness, to suffer from fatigue rather than sleepiness, or to be free of any sleep disorder.
Patient Data
- Ramesh is a 34-year-old man with no major health problems who takes no prescription medicines.
- Sara is a 23-year-old woman with asthma who takes a prescription stimulant daily for treatment.
- Angel is a 72-year-old woman with major depressive disorder who takes a prescription anti-depressant daily.
- John is an 11-year-old child who has been diagnosed with ADD, but does not take any prescription medications.
- Steve is a 54-year-old man with mild heart disease who takes several over-the-counter supplements.
MSLT Results
NOTE: Data given is time until sleep in minutes and seconds. Results may be misleading if they are affected by patient age (different criteria apply for children under 16), noise in the sleep center, patient anxiety during the test, or atypical sleep on the previous night. Use of prescription medications such as stimulants or antidepressants can also lead to misleading results.

The government of Nation X restricts how banks share customers' information with other institutions. For instance, unless a customer explicitly grants permission, no nonpublic information about the customer—e.g., account balances or credit history—can be shared with any non-affiliated institution. Furthermore, banks must allow customers to forbid the sharing of even publicly available information about them, such as listed telephone numbers, with non-affiliated institutions. The bank must honor any decision the customer makes in these cases; however, none of these restrictions limits the sharing of these types of information with any affiliated institutions. All sharing of information other than the types mentioned above is permitted—except that under no circumstances may customers' passwords be shared, even with affiliated institutions. The government of Nation X also requires that banks inform customers of all of these policies.
Select for With an affiliated institution the circumstances under which the government of Nation X allows a bank to share a customer's account balance with an affiliated institution and for With a non-affiliated institution the circumstances under which the government of Nation X allows a bank to share a customer's account balance with a non-affiliated institution. Make only two selections, one in each column.

Option C correct:
The question deals with conditionals. Given data about account balances:
Option C is correct.
unless a customer explicitly grants permission, no nonpublic information about the customer—e.g., account balances or credit history—can be shared with any non-affiliated institution.
Customers explicit granting of permission is necessary for sharing nonpublic information with any non-affiliated institution.
All info can be shared with any affiliated institutions except passwords.
Select for
With an affiliated institution
the circumstances under which the government of Nation X allows a bank to share a customer's account balance with an affiliated institution and for
With a non-affiliated institution
the circumstances under which the government of Nation X allows a bank to share a customer's account balance with a non-affiliated institution.
With an affiliated institution - All circumstances (ANSWER)
The answer here will not be "Upon informing the customer that it will" because the data does not say that the bank must inform the customer that it is going to share the account balance and then share it.
The data only says "The government of Nation X also requires that banks inform customers of all of these policies."
So the bank must inform the customer upon joining that we will share your non public information (except passwords) with affiliated institutions if and whenever asked for. All such policies will be shared with the customer. But the bank does not need to inform the customers before actually sharing this data.
With a non-affiliated institution - Only if a customer has explicitly granted permission (ANSWER)
Customers explicit granting of permission is necessary for sharing nonpublic information with any non-affiliated institution.

statement 1: insufficient
We don't know anything about the reduction
We don't know anything about the reduction
statement 2: insufficient
We don't know anything about the original price. If original was $100, then reduced price would be $50 and the %reduced would be 50%. If original was $200, then reduced price would be $150 and %reduced would be 25%.

statement 1+2: sufficient
We know the original price from statement 1 and with statement 2 we know that the reduced price is $330. We can then figure out the %reduced.

Travis pays 2.5% of 3500, which is $87.5, every 3 months (quarterly).
(525/87.5 = 6), therefore Travis has been paying for (6 x 3 = 18) months now; that is 1.5 years.
