1. Best Flight, Inc., is considering three mutually exclusive alternatives for implementing an automated passenger check-in counter at its hub airport. Each alternative meets the same service requirements, but differences in capital investment amounts and benefits (cost savings) exist among them. The study period is 10 years, and the useful lives of all three alternatives are also 10 years. Market values of all alternatives are assumed to be zero at the end of their useful lives. If the airline's MARR is 10% per year, which alternative should be selected in view of the cash-flow diagrams shown. (Use Future Worth Method) Alternative A: $69,000 LIH 0 10 3 End of Year $390,000 Alternative B: $167.000 ! ! ! ! 0 1 End of Year $920,000 Alternative C: $133,500 !!!! 0 10 2. 3 End of Year $660,000
