2. Three potential energy-efficiency improvements are being considered for your factory. The cash flows for those alternatives are shown below. Assume that the minimum acceptable rate of return is 12% per year. Year Cash Flows for Alternatives A-C A B C 0-$200,000-$250,000 -$230,000 1 100,000 120,000 -15,000 2 100,000 120,000 120,000 3 100,000 120,000 120,000 4 100,000 120,000 120,000 5 100,000 120,000 120,000 6 100,000 120,000 120,000 Use incremental internal rate of return to determine which option should be selected
