Answer:
First, we need to find the rate.
210 = 21x
x = 10
We need to know how much he gets in 35 hours
35x
35(10) = 350
D is your answer.
Let x = number of hours required to fix the computer

To solve for x, subtract $155 from both sides.
$75 = $25x
Divide each side by $25
3 = x
It took 3 hours to fix the computer
