Two electric motors are being considered to power an industrial hoist. Each is capable of providing 100 hp. Pertinent data for each motor are as follows: Motor A Motor B Investment Php 25,000 Php 32,000 Electrical efficiency 88% 84% Maintenance per year Php 400 Php 600 Life, years 10 10 Money is worth 20%. If the expected usage of the hoist is 800 hours per year, what would the cost of electrical power have to be before Motor A is favored over Motor B? (Answer is in Php per kwh.)
