Answer:
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
