The complete question

In a survey, a group of students were asked their favorite sport. eighteen students chose "other" sports, while 37.5% chose football, and 40% chose baseball. how many students chose football

Answer:

Number of student that chose football = 30

Step-by-step explanation:

In a survey student were asked to choose their favorite sports.

The number of student that chose other sport = 18

The percentage number of students that chose football = 37.5%

The percentage number of students that chose baseball = 40%

The whole number of student survey = 100%

percentage number of student that chose other sport = 100% - 37.5% - 40%

percentage number of student that chose other sport = 22.5%

The total number of student surveyed can be computed as

Let the total number of student surveyed = a

22.5/100 * a = 18

22.5a/100 = 18

cross multiply

22.5a = 1800

a = 1800/22.5

a = 80

The number of student that chose football can be computed since the total number of student surveyed is known

Number of student that chose football = 37.5/100 * 80

Number of student that chose football = 3000 / 100

Number of student that chose football = 30
