Russnak Corporation is investigating automating a process by purchasing a new machine for $505,000 that would have a 10 year useful life and no salvage value. By automating the process, the company would save $145,000 per year in cash operating costs. The company's current equipment would be sold for scrap now, yielding $35,000. The annual depreciation on the new machine would be $50,500. (Ignore income taxes.) Required: Determine the simple rate of return on the investment (Round your answer to 1 decimal place.)
