Allison 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 $177
for parts. The total was $623.25. What was the cost of labor, per hour?

ans = $105 per hour

Step-by-step explanation:

first: you subtract the charge for parts from the total and this gives you $446.25.

second: because the technician worked for 4.25 hours = $446.25,if the technician worked for an hour what would be the cost?

4.25hr = $446.25

1 hr      = x . then cross multiply.

4.25x = 446.25 then divide by 4.25 both sides to find th value of x, which is the cost of labour per hour
