Denny Corporation is considering replacing a technologicallyobsolete machine with a new state-of-the-art numerically controlledmachine. The new machine would cost $600000 and would have a10-year useful life. Unfortunately the new machine would have nosalvage value. The new machine would cost $20000 per year tooperate and maintain but would save $125000 per year in labor andother costs. The old machine can be sold now for scrap for $50000.What percentage is the simple rate of return on the new machinerounded to the nearest tenth of a percent? (Ignore income taxes inthis problem.)
