Jackson Incorporated disposes of other companies toxic waste. Currently, Jackson loads the waste by hand into a truck, which requires labor of $30 per load. Jackson is considering a machine that would reduce the amount of time needed to load the waste. The machine would cost $351,000 but would reduce labor cost to $10 per load. Assume that Jackson averages 11,700 loads per year. How many years would it take for Jackson to recover the cost of the new machine?
