Question

In Mr. Walker's 7th grade class, the 30 students created a pie chart showing their choices for favorite pet. Based on the class findings, how many students chose cat as their favorite pet? Explain.

A) 6

B) 10

C) 3

D) 9

Answer 1

D - 9 students

Explanation:

For this problem, you need to find the percentage of students left. Subtracting all the percentages you already know, you get 100 - 30 - 20 - 10 - 10, or 30. Since there are 30 students in the class, 30 percent of 30 is 9 students.

Hopefully this helps- let me know if you have any questions!
