Sheridon Corporation is investigating automating a process by purchasing a new machine for $515,000 that would have a 10 year useful life and no salvage value. By automating the process, the company would save $115,000 per year in cash operating costs. The company's current equipment would be sold for scrap now, yielding $22,000. The annual depreciation on the new machine would be $51,500. (Ignore income taxes.)

Required:

Determine the simple rate of return on the investment.
