Please help show the correct excel formulas. Bascilla, Incorporated is trying to determine the value of several projects. Currently there are four being examined. Compute the Net Present Value of each project. Examine the Internal Rate of Return for each project. Compute the Profitability Index for all projects. Use the PV$()$ function to determine the TVM factors. Be sure to put a $"-"$ sign before the function and for cash out flows, and use $"1"$ as the PMT and FV amounts as necessary. Use the SUM$()$ function in the calculated NPV charts and the Initial Cost in the original data to compute Profitability Index.
