Marvin Industries must choose between an electric-powered and a coal-powered forklift machine for its factory. Because both machines perform the same function, the firm will choose only one. (They are mutually exclusive investments.) The electric-powered machine will cost more, but it will be less expensive to operate; it will cost $102,000, whereas the coal-powered machine will cost $69,500.

The life for both types of machines is estimated to be 6 years, during which time the net cash flows for the electric-powered machine will be $26,150 per year, and those for the coal-powered machine will be $20,000 per year. Annual net cash flows include depreciation expenses. Calculate the NPV and IRR for each type of machine, and decide which to recommend
