Question

Francisco needed to get his computer fixed. He took it to the repair

store. The technician at the store worked on the computer for 5 hours
and charged him $176 for parts. The total was $651. Write and solve an
equation which can be used to determine x, the cost of the labor per
hour.

Answer 1

$95 per hour

Explanation:

The total of charges is the sum of the cost of labor and the cost of parts. The cost of labor is the product of hours (5) and the cost per hour (x). Then the equation for total cost is ...

total cost = parts cost + hours cost

651 = 176 + 5x

475 = 5x . . . . . . . subtract 176

95 = x . . . . . . . . . divide by 5

The cost of labor per hour is $95.
