I have already created the graph, I am looking to better understand the parts in orange. Thanks!

Unit 6 Case (Gitman Chapter 10) Making Norwich Tool's Lathe Investment Decision Norwich Tool, a large machine shop, is considering replacing one of its lathes with either of two new lathes-athe A or lathe B. Lathe A is a highly automated, computer-controlled lathe; lathe B is a less expensive lathe that uses standard technology. To analyze these altematives, Mario Jackson, a financial analyst, prepared estimates of the initial investment and incremental (relevant) cash inflows associated with each lathe. These are shown in the following table. Initial investment CFO) Year 0 Lathe A Lathe B $660,000 $360,000 Cash inflows (CF) $128,000 $88,000 182.000 120,000 166,000 96,000 168,000 86,000 450,000 207.000 2 3 4 5 Note that Mario plans to analyze both lathes over a 5-year period. At the end of that time, the lathes would be sold, thus accounting for the large fifth-year cash inflows. Mario believes that the two lathes are equally risky and that the acceptance of either of them will not change the firm's overall risk. He therefore decides to apply the firm's 13.0% cost of capital when analyzing the lathes. Norwich Tool requires all projects to have a maximum payback period of 4.0 years. To Do a. Use the payback period to assess the acceptability and relative ranking of each lathe. b. Assuming equal risk, use the following sophisticated capital budgeting techniques to assess the acceptability and relative ranking of each lathe: (1) Net present value (NPV). (2) Intemal rate of return (IRR). c. Summarize the preferences indicated by the techniques used in parts (a) and (b). Do the projects have conflicting rankings? d Draw the net present value profiles for both projects on the same set of axes, and discuss any conflict in rankings that may exist between NPV and IRR. Explain any observed conflict in terms of the relative differences in the magnitude and timing of each project's cash flows. e. Use your findings in parts a through d to indicate, on both (1) a theoretical basis and (2) a practical basis, which lathe would be preferred. Explain any difference in recommendations.
