Question

5. This year's enrollment in Mesa School District is

6,000, which is 20 percent higher than last year's.

What was last year's enrollment in Mesa School

District?

Answer 1

The enrollment last year was 5,000

Explanation:

Here, we have the enrollment this year higher than what we have last year by 20%

So we want to know the enrollment last year

Let the enrollment last year be x

Mathematically, the enrollment this year will be;

x + 20% of x = 6,000

Thus;

x + (20/100 * x) = 6000

x + 0.2x = 6000

1.2x = 6,000

x = 6,000/1.2

x = 5,000
