4. Consider the following forecasted cash flows for a project: t 0 1 2 3 4 5 6 CF -410 54 45 67 87 88 96 where today is t=0, one year from today is t=1, etc. In addition, assume that the cash flows are expected to grow after year 6 at a rate of g = -22% (i.e., CFt = (1 + g)CFt-1 for t > 7) in perpetuity. Use Excel to calculate the IRR for this project. (It will be helpful to use Excel's built-in Data -> Solver rather than the built-in IRR or XIRR functions. If it does not appear in your Data tab, you will need to load the Solver Add-in.)
