Enrollment at ELAC decreased by 5%, or 600 people, the year. How many people were enrolled last year?

babymother [125]

Answer:

12,000.

Step-by-step explanation:

Let x be the number of people that were enrolled last year.

We have been given that enrollment at ELAC decreased by 5%, or 600 people, the year. We are asked to find the number of people that were enrolled last year.

We can set as equation such that 5% of x equals 600.

$\frac{5}{100}\cdot x=600$

$0.05x=600$

$\frac{0.05x}{0.05}=\frac{600}{0.05}$

$x=12,000$

Therefore, 12,000 people were enrolled last year.
