Mom's Cookies Inc. is considering the purchase of a new cookie oven. The original cost of the old oven was $35,000; it is now fie years old, and it has a current market value of $15,000. The old oven is being depreciated over a 10-year life toward a zero estimated salvage value on a straight-line basis, resulting in a current book value of $17,500 and an annual depreciation expense of $3,500. The old oven can be used for six more years but has no market value after its depreciable life is over. Management is contemplating the purchase of a new oven whose cost is $27,000 and whose estimated salvage value is zero. Expected before-tax cash savings from the new oven are $4,200 a year over its life you can use bonus depreciation on the oven , and the cost of capital is 10 percent. Assume a 21 percent tax rate. What will the cash flows for this project be?
