Cost Accounting

1)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.)

2)Purchase price is $50 for a part that can be manufactured for $40 per unit; the $40 manufacturing costs include $8 per-unit fixed cost. What is the savings to make rather than to buy?
