Question

Mrs. Walsh conducted a survey of the most popular after school snack in the middle school. Of the 400 students surveyed, 70 preferred muffins, 70 preferred pretzels, 50 preferred fruit, 50 preferred yogurt, 80 preferred cheese and crackers, and 80 preferred granola bars. Select all of the sections of a circle graph that each represent 18

of the entire circle.

Answer 1

Muffins and Pretzels

Explanation:

Muffins: 70/400 = 0.175 or 17.5

Pretzels: 70/400 = 0.175 or 17.5

17.5 is closest to 18%

So, the sections of the circle graph that represent 18% of the entire circle are muffins and pretzels, since they are closest to 18%

Answer 2

the sections of the circle graph that represent 18% of the entire circle are none of them, since none of the categories represent exactly 18% of the surveyed students.
