Your task is to choose projects from the given portfolio that will maximize overall Net Present Value $($NPV$)$ but fit the investment budget of $2$M $.$ Set up the problem in Excel and use solver to figure out what projects to abandon. if you don$$t feel confident how to set up the problem in Excel or how to use solver, practise with $3\_1\_$solver$\_$practice.xls$.$ No need to submit this file. Here is the portfolio: Project Investment NPV $125000024000027800001050000330000100004390007400058300001000000656000900007490000630000819500011000095000005000010110000150000$ Calculate projects profitability indices $($PI$).$ PI in commonly used to rank investment opportunities. since NPV already contains initial investment, the formula would be PI $=$ NPV $/$ Investment $+1$ Sort the projects by PI$.$ Are projects with lowest PI are abandoned? Why? Provide your answer in a short comment. you might want to play with the model manually to understand why.
