3. Consider the two mutually exclusive investment alternatives given in the table below. n 10123 Project A -$12,000 $5,000 $6,000 $7,000 Project B -$10,000 $9,000 $8,000 -$1,000 L a. Calculate the IRR for Projects A and B (use RIC if there are multiple i*). (10 points) b. Calculate the IRR on incremental investment (use RIC if there are multiple i*). Which project is to be selected? Assume that MARR=8%. (10 points) c. Calculate the MIRR of Project B. Assume that MARR-8%. (10 points)
