or discount factors use Exhibit 128.1 and Exhibit 128.2. All scenarios are independent of all other scenarios. Assume that all cash flows are after-tax cash flows. a. Kambry Day is considering investing in one of the following two projects. Either project will require an investment of $20,000. The expected cash flows for the two projects follow. Assume that each project is depreciable. Year Project A Project B 1 $ 6,000 $ 6,000 2 8,000 8,000 3 10,000 10,000 3,000 4 10,000 5 10,000 3,000 b. Wilma Golding is retiring and has the option to take her retirement as a lump sum of $450,000 or to receive $30,000 per year for 20 years. Wilma's required rate of return is 6% c. David Booth is interested in investing in some tools and equipment so that he can do independent drywalling. The cost of the tools and equipment is $30,000. He estimates that the return from owning his own equipment will be 39.000 per year. The tools and equipment will last 6 years. d. Patsy Folson Is evaluating what appears to be an attractive opportunity. She is currently the owner of a small manufacturing company and has the opportunity to acquire another small company's equipment that would provide production of a part currently purchased externally. She estimates that the savings from internal production will be $75,000 per year. She estimates that the equipment will last 10 years. The owner is asking $400,000 for the equipment Her company cost of capital is 89 Required: Required: 1. Conceptual Connection: What is the payback period for each of Kambry Day's projects? Round your answers to two decimal places. Project A years Project B years If rapid payback is important, which project should be chosen? Project A 2. Conceptual Connection: Which of Kambry's projects should be chosen based on the ARR? If required, round to the nearest percent Accounting rate of return (ARR): Project A: ARR 9% Project B: ARR % Project A 3. Assuming that Wilma Golding will live for another 20 vears, should she take the lump sum or the annuity? wilma should take the fump sum. 4. Assuming a required rate of return of 8% for David Booth, calculate the NPV of the investment. If required, round to the nearest dollar NPV S 5. Calculate the IRR for Patsy Folson's project. Round your answer to the nearest percent. % Should Patsy acquire the equipment? Yes
