Explanation:

Question 3a

Step1: Find total students

Total students = 13 (Apples) + 25 (Bananas) + 12 (Oranges) = 50

Step2: Find number of students who voted for Apples or Bananas

Number of students = 13 + 25 = 38

Step3: Calculate percentage

Percentage = $\frac{38}{50} \times 100 = 76\%$

Step1: Find total students (from 3a, total is 50)

Step2: Find number of students who did not vote for Apples

Number of students = 50 - 13 = 37

Step3: Calculate percentage

Percentage = $\frac{37}{50} \times 100 = 74\%$

Step1: Recall tax rate formula

Tax rate = $\frac{\text{Tax}}{\text{Total Cost}} \times 100$

Step2: Substitute values

Tax = $6, Total Cost = $75
Tax rate = $\frac{6}{75} \times 100 = 8\%$

Answer:

76%
