Santamaria Corporation wishes to select the best of three possible computers, each expected to meet the firm's growing need for computational and storage capacity. The three computersA, B, and Care equally risky. The firm plans to use a 12 % cost of capital to evaluate each of them. The initial outlay and annual cash outflows over the life of each computer are shown in the following table. Cash Flows Year Computer A -$55,000 Computer B -$40,000 Computer C -$70,000 -$8,000 -$6,000 -$15,000 -$8,000 -$13,000 -$15,000 -$8,000 -$17,000 -$15,000 -$8,000 -$24,000 -$15,000 -$8,000 -$15,000 -$15,000 -$8,000 Required: a) Calculate the NPV for each project over its life. Rank the projects in descending order based on NPV. (Marks: 4) b) Use the equivalent annual cost (EAC) approach to evaluate and rank the projects in descending order based on the EAC. (Marks: 4) Compare and contrast your findings in parts (a) and (b). Which project would you recommend that the firm purchase? Why? (Marks: 2) Please show your calculations clearly
