What is Kelly's regular pay per hour?

Answer 1

What is Kelly's regular pay per hour?
(A) $20 per hour
(B) $10 per hour
(C) $12 per hour
(D) $16 per hour

Answer 2

Let x = K's pay per regular hour
Then, K's pay per overtime hour is (x + 10)

8x + 4(x + 10) = 160
8x + 4x + 40 = 160

Solve for x to get K's pay per regular hour @StudiousHojea

Answer 3

(B) $10 per hour
8x+4(x+10)=160
x=10 dollars
