Question

Thirty-six members of the middle school choir, or 30% participated in the regional contest, as shown in the model below.

How many total students are in the choir?

Answer 1

There are 120 students in the choir.

Explanation:

Given that:

Number of members who participated in contest = 36

This represents 30% of the total members of choir at the school.

Let,

x be the number of total sutdents

30% of x = 36

`(30)/(100)x=36`

0.3x = 36

Dividing both sides by 0.3

`(0.3x)/(0.3)=(36)/(0.3)\\x=120`

Hence,

There are 120 students in the choir.
