Answer:

$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.
