Let x = Kathleen’s weekly salary BEFORE the increase

GIVEN: Kathleen’s weekly salary was increased by 8 percent to $237.60
We can write: x + (8% of x) = 237.60
Simplify: x + 0.08x = 237.60
Simplify: 1.08x = 237.60
Solve: x = 237.60/1.08 = 220

Kathleen's salary BEFORE the increase was $220

Cheers,
Brent
