Answer 1

Missing:

If Hector earned $126 last week, what was the amount of Hector's raise per hour?

Answer:

`x = 2.5`

Explanation:

Given

`y=12(8+x)`

Required

Solve for x when y = 126

`y=12(8+x)`

`126 = 12(8 + x)`

Divide through by 12

`(126)/(12) = (12(8 + x))/(12)`

`10.5 = 8 + x`

`x = 10.5 - 8`

`x = 2.5`
