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
