Use Exhibit 128.1 and Exhibit 128.2 to locate the present value of an annuity of 51 , which is the amount to be multiplied times the future annual cash fow amount. Each of the following sceparios is independenti Assume that all cash flows are after-tax cash flows. a. Campbell Manufacturing is considering the purchase of a new welding system. The cash benefits will be $480, 000 per year. The system costs $3,150,000 and will last 10 years. b. Evee Cardenas is interested in investing in a women's specialty shop. The cost of the investment is 5330,000 . She estimates that the return from owning her own shop will be $50,000 per year. She estimates that the shop will have a useful life of 6 years. c. Barker Company calculated the NPV of a project and found it to be $63,900. The project's life was estimated to be 8 years. The required rate of retum used for the NPV calculation was 10%. The project was expected to produce annual after-tax cash flows of $135,000. Requiredt 1. Compute the NPV for Campbeli Manufacturing, assuming a discount rate of 12%, If required, round all present value calculations to the nearest doliar. Use the minus sign to indicate a negative NPV. Should the company buy the nIw welding system? 2. Conceptual Connection: Assuming a required rate of return of 8%, calculate the NPV for Evee Cardenas' investment. Round to the nearest dollar. If required, round all present value calculations to the nearest dollar. Use the minus sign to indicate a negative NPV. Should she invest? What if the estimated return was $135,000 per year? Calculate the new NPV for Evee Cardenas' investment. Would this affect the decision? What Joes this tell you about your analysis? Round to the nearest dollar. 3. What was the required investment for Barker Company's projct? Round to the nearest dollar. If required, round all present value calculations t he nearest dollar
