Jackson Inc. disposes of other companies toxic waste. Currently Jackson loads the waste by hand into the truck, which requires labor of $25 per load. Jackson is considering a machine that would reduce the amount of time needed to load the waste. The machine would cost $252,500, but would reduce labor cost to $4 per load. The machine averages 10,100 loads per year. How long will it take Jackson to recover the cost? (Round your answer to 2 decimal places.)
