Required: Jackson Incorporated disposes of other companies toxic waste. Currently, Jackson loads the waste by hand into a truck, which requires labor of $35 per load. Jackson is considering a machine that would reduce the amount of time needed to load the waste. The machine would cost $392,000 but would reduce labor cost to $5 per load. Assume that Jackson averages 11,200 loads per year. How many years would it take for Jackson to recover the cost of the new machine? (Round your answer to 2 decimal places.)
