Answer:

12.75

Step-by-step explanation:

Answer:he was making $2100 before the raise

Step-by-step explanation:

Let x represent the amount that he was making before the raise.

This week Aaron got a promotion at work that came with a 3 % pay increase. This means that the value of the raise is

3/100 × x = 0.03 × x = 0.03x

The new salary would be

0.03x + x = 1.03x

If now his monthly salary is $2163, it means that

1.03x = 2163

x = 2163/1.03 = 2100
