Step-by-step explanation:
We can write a proportion to find the total amount in the choir using the information given. A proportion is two equivalent ratios set equal to each other. Since we know the strength of students increased by 8% to 2160 then the original was 92%.

We will cross multiply the numerator of one ratio with denominator of the other. And then solve for y.
92(2160)=100(y)
