Answer:
3 hours
Step-by-step explanation:
Total cost = 144 + 80h
Where h = number of hours
How many hours can Michelle afford to pay the mechanic if she can spend no more than $384?
384 = 144 + 80h
Subtract 144 from both sides
384 - 144 = 144 + 80h - 144
384 - 144 = 80h
240 = 80h
Divide both sides by 80
h = 240 / 80
= 3
h = 3 hours
