1. Consider the following set of projects from Problem Set 1. Assume MARR = 10%. Project 1:0 1 -100 50 -100 30 -16 92 2 50 30 -170 3 4 50 50 30 10 100 6 -20 100 6 -760 10 2 (a) Recall the criteria for having a unique IRR value for a project. Apply these criteria to the above projects and identify which ones are guaranteed to have a unique IRR. (b) For each project, write down an equation that will give the project's IRR as its solution. () (SPR) Compute the IRR for each project and determine which ones are economi- cally feasible. You can use a spreadsheet, but you must also supply the equation the solution to which gives the IRR value. (d) Find the breakeven periods for the three projects
