Jackson Inc. disposes of other companies toxic waste. Currently, Jackson loads the waste by hand into a 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 $290,000 but would reduce labor cost to $6 per load. Assume that Jackson averages 11,600 loads per year. How many years would it take for Jackson to recover the cost of the new machine?
