Mars Engineering Industries must choose between a gas-powered and an electric- powered generator for their factory. Both generators perform the same function. The electric-powered generator will cost $20,000 and the gas-powered generator will cost $16,500. The life of each type of generator is estimated to be 5 years during which time the net cash flow per year for gas-powered generator will be $5,000 and that for electric-powered generator will be $6,500. The cost of capital for Mars is 13%. Calculate IRR and MIRR for each generator and decide which to recommend.
