Understanding the Problem
To find the number of questions the student solved on the 5th day, we need to ensure that the average number of questions solved over the five days is at least 14.
Current Data
The questions solved over the past four days are:
- Day 1: 8
- Day 2: 10
- Day 3: 16
- Day 4: 18
Calculating the Total Questions Solved
First, let’s calculate the total number of questions solved in the first four days:
- Total = 8 + 10 + 16 + 18 = 52
Mean Requirement
To find the required number of questions for the 5th day (let's call it "x"), we need to set up the equation for the mean:
- Mean = (Total questions solved) / (Number of days)
We want the mean to be at least 14:
- (52 + x) / 5 ≥ 14
Solving the Inequality
1. Multiply both sides by 5:
- 52 + x ≥ 70
2. Subtract 52 from both sides:
- x ≥ 18
Conclusion
To meet the requirement of an average of at least 14 questions solved per day, the student must solve at least:
- 18 questions on the 5th day.
This ensures that the total number of questions solved over five days is sufficient to achieve the desired average.
