Question

Scott works on cars. He charges $35 for each car plus $7 per hour. How many hours did he work on Kylie's car if
her bill was $63?

Answer 1

It would be 4 extra hours.

35(car) plus 7(h)

If we want to get to 63, you take 35 plus some multiple of 7. In this case, 7 x 4 is 28,
35 + 28 = 63

Therefore, your answer is 4 hours.
