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.

Please help on number 2?!?!?
Rainbow [258]
Basically, the higher the price an item is the more you will be taking off of it if it is 10 percent off. For example, at $50, 10 percent off is $5, but at $55, it’s $5.50. There is more to take away, making the final price less than the original. Hope that make sense!
