Question 2 R=1 R is the 8th digit of your student number. For example, student number = 19012345A, R = 5. The following data have been estimated for two mutually exclusive investment alternatives, A and B, associated with an engineering project for which revenues as well as expenses are involved. Alternative A B Initial Investment $ (3,500,000+ R x 1,000) $ (5,000,000 + R x 1,000) Annual Revenues $ (2,255,000+ Rx 1,000) $ (2,880,000+ Rx 1,000) Annual Expenses $ (1,000,000+ Rx 1,000) $ (1,400,000+ Rx 1,000) Useful life 4 6 NIL Salvage value at the end of NIL the project's useful life Minimum acceptable rate of return (MARR) is 10% per year. (a) Use the repeatability assumption. For a study period of 12 years, which alternative is more desirable based on Present Worth (PW) analysis? (7 marks) (b) Use the repeatability assumption. For a study period of 12 years, which alternative is more desirable based on Annual Worth (AW) analysis? (7 marks) (c) Use co-terminated assumption. For a study period of 6 years, which alternative is more desirable based on Future Worth (FW) analysis? (8 marks) (d) Under what condition of the study period the repeatability assumption may be used? (3 marks)
