Question

Write an equation as part of solving the problem.The cost to replace a water pump in a Corvette was $255. This included $95 for the water pump plus $80/h for labor. How many hours of labor were required to replace the water pump?

Answer 1

cost of replacing a water pump= C = $ 255

water pump cost = $95

Hour of labor = $80 per hour

Number of hours of labor = x

255 = 95 + 80x

Solve for x

255 - 95 = 80x

160 = 80x

160/80 = x

x = 2 hours
