Answer:
C) 3
Step-by-step explanation:
First we need to subtract the one-time payment for the car parts from the total bill: $274-$49=$225
Now we can find out how many hours of work were done. To do so we set up an equation like this:
(total bill) ÷ (amount per hour) = (How many hours of work)
Plug in your numbers:
$225 ÷ $75 = 3
So there were three hours of work done on Mrs.Bakers's car.
