The management of Kunkel Company is considering the purchase of a $21,000 machine that would reduce operating costs by $5,000 per year. At the end of the machine's five-year useful life, it will have zero salvage value. The company's required rate of return is 12%. Click here to view Exhibit 128-1 and Exhibit 128-2. to determine the appropriate discount factor(5) using table. Required: 1. Determine the net present value of the investment in the machine. 2. What is the difference between the total, undiscounted cash inflows and cash outflows over the entre life of the machine? Complete this question by entering your answers in the tabs below. Determine the net present value of the investment in the machine. (Negative amounts should be indicated by a minus sign. Round your final answer to the nearest whole dollar amount. Use the appropriate table to determine the discount factor(s).) What is the difference between the total, undiscounted cash inflows and cash outflows over the entire life of the machine? (Any cash outflows should be indicated by a minus sign.) Total difference in undiscounted cash inflows and outfiows 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 128-1 and Exhibit 128-2, to determine the appropriate discount factor(s) using tables. Required: 1. What would bo the total annual cash inflows associated with the new machine for capital budgeting purposes? 2. What discount factor should be used to compute the thew machine's internal rate of return? (Round your answers to 3 decimal places.) 3. What is the new machine's internal rate of return? (Round your final answer 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 intemal 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.)
