Wendell's Donut Shoppe is Investigating the purchase of a new $$39,600$ donut$-$making machine. The new machine would permit the

company to reduce the amount of part$-$time help needed, at a cost savings of $$5,400$ per year. In addition, the new machine would

allow the company to produce one new style of donut, resulting in the sale of $2,500$ dozen more donuts each year. The company

realizes a contribution margin of $$2\mathrm{.}00$ per dozen donuts sold. The new machine would have a slx$-$year useful life.

Required:

What would be the total annual cash Inflows assoclated with the new machine for capital budgeting purposes?

What discount factor should be used to compute the new machine's Internal rate of return? $($Round your answers to $3$ decimal

places.$)$

What is the new machine's internal rate of return? $($Round your final answer to the nearest whole percentage.$)$

In addition to the data glven previously, assume that the machine will have a $$11,780$ salvage value at the end of sIx years. Under

these conditions, what is the internal rate of return? $($Hint: You may find it helpful to use the net present value approach; find the

discount rate that will cause the net present value to be closest to zero.$)($Round your final answer to the nearest whole percentage.$)$
