Answer:
$35 per hour
Step-by-step explanation:
The total charge is the sum of costs of parts and labor. If h is the cost of a labor hour, then we have ...
188.75 = 75 + 3.25h
113.75 = 3.25h . . . . . . . . subtract 75
113.75/3.25 = h = 35 . . . divide by the coefficient of h
The cost of labor, per hour, is $35.
