You need to determine i* per year for the cash flows shown below. Since you have a new boss, you decided to perform a thorough analysis. Do the following:
(a) Use a spreadsheet to find i*.
(b) Develop two charts on the spreadsheet: a column chart that plots cash flows versus year, and a scatter chart showing PW values versus a range of i values, one of which is i*. (Hint: Use Figure 7–4 as a guide.)
(c) You were told when handed the estimates that the rate of return was about 25%. Determine the cash flows for years 2, 3, and 4 that are necessary to realize an i* of 25% per year, if they remain in the same proportion to each other as initially estimated.
