Question

mrs. redd paid $124 to get her car repaired. the total cost of the repairs was the sum of the amount paid for parts and labor. she was charged $76 for parts and $32/ hour for labor. how many hours did it take to fix her car

Answer 1

Let x = the number of hours of labor

parts + labor = total cost

76+32x=124

Subtract 76 from both sides ans simplify

76+32x-76=124-76

32x=48

Divide 32 by both sides and simplify

32x/32=48/32

x = 1.5 hours of labor for the car repair
