Q1. At a gym there are three different paths an individual can take to obtaining membership. The first option is personal training. The second option is group fitness classes and the last option is individual direction. Members are only allowed to partake in individual direction after 5 personal training sessions and 10 group fitness classes.
Personnel
For personal training, there must be one trainer per individual. For group fitness classes there must be one trainer per eight individuals. For individual direction, no trainer is required; however, only 25 members can partake in individual direction at a time. At this particular gym there are 12 trainers.
Price
The price of membership depends on the technique the individual chooses. Personal training costs between $40 and $75 per session, depending on the trainer. Group fitness classes cost $20 per session. Individual direction costs $15 per visit.
Based on the given information, determine whether each of the statements is justified.

I. An individual who is experienced in fitness and has taken 3 group classes can choose to pay for the individual direction membership.
II. An individual who has a budget of $160 a month to spend on fitness after going through the personal training and group sessions can attend 8 classes per month.
III. Tina has completed all the necessary requirements to have an individual direction membership; Tina would make the 26th member of this type.

Explanation:

Look at each of the statements and the given information in the paragraphs to determine whether they are justified or not.

I. An individual who is experienced in fitness and has taken 3 group classes can choose to pay for the individual direction membership.
Look at the bolded sentence in the techniques paragraph:

At a gym there are three different paths an individual can take to obtaining membership. The first option is personal training. The second option is group fitness classes and the last option is individual direction. Members are only allowed to partake in individual direction after 5 personal training sessions and 10 group fitness classes.

Therefore, statement I is not justified.

II. An individual who has a budget of $160 a month to spend on fitness after going through the personal training and group sessions can attend 8 classes per month.
Look at the bolded sentence in the price paragraph:

The price of membership depends on the technique the individual chooses. Personal training costs anywhere between $40 and $75 per session depending on the trainer. Group fitness classes cost $20 per session and individual direction costs $15 per visit.

8 classes a month × $20 = $160

Therefore, statement II is justified.

III. Tina has completed all the necessary requirements to have an individual direction membership; Tina would make the 26th member of this type.
Look at the bolded sentence in the personnel paragraph:

For personal training, there must be one trainer per individual. For group fitness classes there must be one trainer per eight individuals. For individual direction, no trainer is required; however, only 25 members can partake in individual direction at a time. At this particular gym there are 12 trainers.

Therefore, statement III is not justified.

Q2. Pointillism is a type of art that is created by drawing numerous dots on paper. Watercolor paintings are created by combining paint and water to create different shades. Pottery is made by molding clay.

Time to Create a Piece
A pointillism piece that has dimensions of 12 x 18 takes on average 15 hours to create. A watercolor painting that is 17 x 23 takes on average 20 hours to create. A piece of pottery that has dimensions 6 x 2 x 4 takes 12 hours to create.

Exposition
An art school is holding an exposition to highlight their student artists. The school will commission their students to create new works of art specifically for the exposition. The exposition requires one-third of the artwork displayed to be watercolor paintings and one-fifth to be pottery pieces.

Based on the given information, determine whether each of the statements is justified.

I. There are 20 watercolor paintings, 12 pottery pieces, and 28 pointillism pieces in the art exposition.
II. Students that will be featured in the school’s exposition require no more than one day’s notice.
III. Timothy is known for his watercolor pieces and is expected to paint 4 for the school’s exposition. Timothy can create all the pieces over the weekend (Saturday and Sunday).

Explanation: 
I. There are 20 watercolor paintings, 12 pottery pieces, and 28 pointillism pieces in the art exposition.
Looking at the bolded sentence from the third paragraph,
A art school is holding an exposition to highlight their student talent. The exposition requires a third of the artwork to be watercolor paintings and a fifth to be pottery pieces.
20 + 12 + 28 = 60
20 ÷ 60 = 1⁄3 = Watercolor
12 ÷ 60 = 1⁄5 = Pottery
Therefore statement I is justified.
II. Students that will be featured in the school’s exposition require at least a day’s notice.
Looking at the bolded sentence from the second paragraph,
A pointillism piece that has dimensions of 12×18 takes on average 15 hours to create. A watercolor painting that is 17×23 takes on average 20 hours to create. A piece of pottery that has dimensions 6×2×4 takes 12 hours to create.
Since the longest an art piece takes to create is 20 hours, one day’s notice, although not ideal, is acceptable. Therefore, statement II is justified.
III. Timothy is known for his watercolor pieces and is expected to paint 4 for the school’s exposition. Timothy can create all the pieces over the weekend (Saturday and Sunday).
Since a watercolor painting takes 20 hours and Timothy needs to create four, it will take him 80 hours total. There are only 24 hours in a day, and Saturday plus Sunday gives 48 hours, so statement III is not justified.
