Blaine Corporation is considering replacing a technologically obsolete machine with a new state-of-the-art numerically controlled machine. The new machine would cost $330,000 and would have a twelve-year useful life. Unfortunately, the new machine would have no salvage value. The new machine would cost $56,000 per year to operate and maintain, but would save $97,000 per year in labor and other costs. The old machine can be sold now for scrap for $33,000. The simple rate of return on the new machine is closest to: (Ignore income taxes in this problem.) 4.09% 29.39% 9.09% 4.55%
