Audrey needed to get her computer fixed. She took it to the repair store. The technician at the store worked on the computer for 4.25 hours and charged her $156 for parts. The total was $347.25. What was the cost of labor, per hour?

 

ANSWER: 

So in this problem, we know:
cost of parts= $156
number of hours= 4.25
total cost= $347.25
In order to solve it we must do an unwinding: cost of all hours labor= total cost−cost of parts
=  347.25−156
=  191.25

so 191.25/4.25 = 45,  ANSWER: $45 AN HOUR

    In order to solve it we must do an unwinding:
    cost of all hours labor= total cost−cost of parts
    =
    347.25−156
    =
    191.25
    so 191.25/4.25 =
