Suppose your give cash flow data of 3 project alternatives in the table below with 4 years of useful lives each and a study period of 4 years under consideration. Assume an MARR of 11.06% compounded semiannually. Investment Cost 1st Year Revenue 2nd Year - Revenue 3rd Year Revenue Salvage Value Alpha $ 70,000 $ 40,000 $ 50,000 $ 60,000 $ 22,750 Beta $ 50,000 $ 30,000 $ 40,000 $ 50,000 $ 5,000 Gamma 120,000 $ 60,000 $ 60,000 $ 60,000 $ 46,000 Using Present Worth Analysis, what is the present worth of Project Alpha? (Assume that your final numerical answers is rounded off up to 2 decimal places and is in terms of dollars.) Using Present Worth Analysis, what is the present worth of Project Beta? (Assume that your final numerical answers is rounded off up to 2 decimal places and is in terms of dollars.) Using Present Worth Analysis, what is the present worth of Project Gamma? (Assume that your final numerical answers is rounded off up to 2 decimal places and is in terms of dollars.) Using Present Worth Analysis, what is the best project alternative? (Type 'A' for Alpha, 'B' for Beta, or 'G' for Gamma).
