Question

3) Eric had $30 when he started a job that paid him $9 an hour. Which equation below would represent the

amount of money Eric has, y, and the amount of hours he has worked, x?
A. y = 30x + 9
B. y = 9x - 30
C. y = -9x + 30
D. y = 9x + 30

Answer 1

D. y = 9x + 30.

Eric has thirty dollars when he starts, so he would be adding 30, and since he makes 9 dollars an hour, it would be 9x. therefore the answer is 9x + 30
