(ignore income taxes in this problem.) blaine corporation is considering replacing a technologically obsolete machine with a new state-of-the-art numerically controlled machine. the new machine would cost $180,000 and would have a ten-year useful life. unfortunately, the new machine would have no salvage value. the new machine would cost $12,000 per year to operate and maintain, but would save $48,000 per year in labor and other costs. the old machine can be sold now for scrap for $20,000. what is the simple rate of return on the new machine (round off your answer to the nearest one-hundredth of a percent)? select one:
1) 10.00%2) 26.67%3) 22.50%4) 11.25%show work
