Problem
George has just finished the cost analysis of a brass pump with and without an interior coating. The brass pump will last 3 years, but if an interior coating is applied, less energy will be needed for pumping. The interior coating costs $300, and the energy savings is $120 per year. George claims that the coating will save $60. Is George's work correct? If not, what has George done wrong?
