Dorothy & George Company is planning to acquire a new machine at a total cost of $57,200. The machine's estimated life is 6 years and its estimated salvage value is $500. The company estimates that annual cash savings from using this machine will be $12,000. The company's after-tax cost of capital is 7% and its income tax rate is 40%. The company uses straight-line depreciation. (Use Appendix C, Table 1 and Appendix C, Table 2.) (Do not round intermediate calculations. Negative amounts should be indicated by a minus sign. Round answers to the nearest dollar amount.) Required: 1. What is this investment's net after-tax annual cash inflow? 2. Assume that the net after-tax annual cash inflow of this investment is $8,000; what is the net present value (NPV) of this investment? 3. What are the minimum net after-tax annual cost savings that make the proposed investment acceptable (i.e., the dollar cost savings that would yield an NPV of $0)? Hint: Redo the NPV analysis by setting the NPV equal to zero and making the annual after-tax cash flows equal to X; then solve for X and enter the amount as your answer. Also consider using Goal Seek in Excel. 1 Net after-tax annual cash inflow Net present value 2. 3.
