Use functional symbols (factors) to show your logic. a) If the study period is 9 years; i.e., the product life is expected to be 9 years, which alternative should be chosen? State the main assumptions made. b) If the study period is 6 years, i.e., the product life is expected to be 6 years, which alternative should be chosen? State the main assumptions made. c) Do you expect the best alternative chosen in (a) and (b) to be always the same? Explain your answers. d) If the study period is 3 years, i.e., the product life is expected to be only 3 years, which alternative should be chosen using any Discounted Cash Flow Method? State the main assumptions made. e) If the study period is 3 years, i.e., the product life is expected to be only 3 years, determine which alternative should be chosen using the IRR Method. You may use any equation solver to compute IRRs after stating the relevant equations that need to be solved. f) Do you expect the best alternative chosen in (d) and (e) to be always the same?
