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?

The enrollment last year was 5,000

Step-by-step 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

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150
