Consider the following investment projects: (20 pts) Project Cash Flow B n A - $100 0 -$5 1 100 24 -$100 30 30 70 2. 10 30 -40 3 4 70 5 a) Classify each project as either simple or non-simple. (5 pts) b) Use the quadratic equation method to compute i* for A. (5 pts) c) Using the result of part b) and if the IRRs for projects B and C are: IRR = 28.59% and IRRC = 15.57%, apply the net-investment test to determine whether they are pure or mixed investment projects. (5 pts) d) Evaluate each project's acceptability at MARR 18% (5 pts)
