Coach Ellis surveyed a sample of students about their favorite sport. The circle graph below shows

some of the percents to represent the results. 100 students chose football.
How many students chose swimming as their favorite sport?

Answer 1

C. 120 students

setup proportion:

25/100 = 30/x

25x = 100(30)

25x = 3000

x = 120
