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

Answer:

There are 120 students in the choir.

Step-by-step 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

$\frac{30}{100}x=36$

0.3x = 36

Dividing both sides by 0.3

$\frac{0.3x}{0.3}=\frac{36}{0.3}\\x=120$

Hence,

There are 120 students in the choir.
