A repair bill for your car is $553. The parts cost $265. The labor cost is $48 per hour. Write and solve an equation to find the number of hours tt of labor spent repairing the car.
553=265+48t t=6
Explanation:
Let R be the repair bill Let P be the cost of parts Let L be the labor cost
R=P+L
R=553 P=265
553=265+L
Let t be the labor duration Let r be the labor rate
L=rt
r=48
⇒L=48t
⇒553=265+48t ⇒288=48t ⇒t=6
