"A firm is considering purchasing a computer system.
-Cost of system is $191,000. The firm will pay for the computer system in year 0.
-Project life: 5 years
-Salvage value in year 0 (constant) dollars: $13,000
-Depreciation method: five-years MACRS
-Marginal income-tax rate = 37% (remains constant over time)
-Annual revenue = $146,000 (year-0 constant dollars)
-Annual expenses (not including depreciation) = $77,000 (year-0 constant dollars) If the general inflation rate is 3.7% during the project period (which will affect all revenues, expenses, and the salvage value but not depreciation), determine the INFLATION-FREE IRR' of the computer system. Enter your answer as a percentage between 0 and 100."
