Question

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

Answer 1

1260

Explanation:

Since we have to predict, we can use ratios to help us solve this.

12 said yes out of 72 randomly chosen, SO,

if 210 would say yes (goes to play), how many is total??

12 is to 72 AS 210 is to HOW MUCH (let it be x)??

We can setup ratio, cross multiply, and solve for x:

`(12)/(72)=(210)/(x)\\12x=210*72\\12x=15,120\\x=(15,120)/(12)\\x=1260`

around 1260 students attend the school
