r11(1+r)1 Wendell's Donut Shoppe is investigating the purchase of a new $37,700 donut-making machine. The new machine would permit the company to reduce the amount of part-time help needed, at a cost savings of $6,600 per year. In addition, the new machine would allow the company to produce one new style of donut, resulting in the sale of 1,500 dozen more donuts each year. The company realizes a contribution margin of $2.00 per dozen donuts sold. The new machine would have a six-year useful life. Click here to view Exhibit 781 and to determine the appropriate discount factor(s) using tables. Required: 1. What would be the total annual cash inflows associated with the new machine for capital budgeting purposes? 2. What discount factor should be used to compute the new machine's internal rate of return? Note: Round your answers to 3 decimal places. 3. What is the new machine's internal rate of return? Note: Round your final onswer to the nearest whole percentage. 4. In addition to the data given previously, assume that the machine will have a $14,130 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.) Note: Round your final answer to the nearest whole percentage. EXHIBIT 7E-1 Preseat Valme of $1;(1+)21 Perit Industries has $135,000 to invest. The company is trying to decide between two alternative uses of the funds.

Click here to view Exhibit 78.1 and Exhibit 78-2. to determine the appropriate discount factor(s) using tables. Required: 1. Compute the net present value of Project A. Note: Enter negative values with a minus sign. Round your final answer to the nearest whole dollar amount. 2. Compute the net present value of Project B. Note: Enter negative values with a minus sign. Round your final answer to the nearest whole dollor amount. 3. Which investment alternative (if either) would you recommend that the company accept
