Messersmith Corporation is investigating automating a process by purchasing a machine for $688,000 that would have an 8 year useful life and no salvage value. By automating the process, the company would save $160,000 per year in cash operating costs. The new machine would replace some old equipment that would be sold for scrap now, yielding $19,000. The annual depreciation on the new machine would be $86,000. The simple rate of return on the investment is closest to: A) 23.3% B) 11.1% C) 10.8% D) 12.5%
