Question

a mechanic charged $220.28 to repair a car the price included charges for e hours of labor and 126.53 for parts how much does the mechanic charge per hour for labor

Answer 1

Take 220.28 and subtract 126.53 to get 93.75.  This 93.75 is equal to e hours of labor.  So if you knew that they worked on the car say for 2 hours you would divide 93.75 by two, if three hours divide by three and so on.  If they worked on the car for one hour as we can assume.  The mechanic charges $93.75 per hour.

Answer 2

$31.25, I took 220.28 subtracted 126.53, then with the number I got I divided it by three and got 31.25.
