ECON 423 Illinois Institute of Technology 9 You are evaluating First Problem Set Due: February 2, 2017 The Banner l costs two different database management systems for IIT's admissions department. The $800,000, has a six-year and has operating costs of of its Banner ll costs $1,200,000, has nine-year life, and has operating costs of only $65,000 per year. The salvage value (received at the end of its useful life) of each machine is equal to ten percent initial cost. Since the useful lives are unequal, you decide to use equivalent uniform cost analysis. In addition, because IIT is a not-for-profit entity, you realize that income taxes are irrelevant to your analysis- a. Assuming that the relevant interest rate is 8% which system should you recommend? b. Now, calculate the (net) present value of each proposal remembering to use a common investment period, e.g., eighteen years, thirty-six years, fifty-four years. or forever (My would be "forever")
