Question

Kelvin just received a 3% raise at work. His new pay is $11.00 per hour. What was Kelvin's hourly pay before the raise?

Answer 1

$10.68

Explanation:

He was starting with an hourly rate of ___. But he had his hourly pay increased by 3%. We add that extra 3% onto the 100% he was originally being paid with. So with this information, we get 103%. His 103% was getting him paid $11. So, here's what we do...

Step One:
100% starting pay + 3% raise. = 103% current pay.

Step Two:

`(103)/(100\\)` = 1.03
`(11)/(1.03)` = 10.679
or
$10.68 per hour.
