Consider the following table which shows information for five mutually exclusive alternatives. The MARR is 15%: Year A B D E 0 -400 -300 -100 -500 -200 1 126 83 37 150 69 2 126 83 37 150 69 3 126 83 37 150 69 4 126 83 37 150 69 5 126 83 37 150 69 PWB 422 278 124 503 231 B/C 1.06 0.93 1.24 1.01 1.16 ROR 17.3% 11.9% 24.8% 15.2% 21.4% Based on this information, what would be the incremental ROR for increment E-C? You can round off to the nearest percent before choosing from the answers provided
