a survey asked 72 randomly chosen students if they were going to attend the school play. twelve said yes. if there are 210 tickets sold for the play, predict the number of students who attend the school.

Respuesta :

We can solve this by setting up a proportion:

12 seeing the play/ 72 students = 210 seeing the play/ x students

We can cross multiply to solve for x:

(12)x=(72)(210)
12x=15,120
x=1,260 students who attend the school
