Facts and assumptions Initial cost (5000) $28,000 Unit sales (000) 400 Selling price per unit, year 1 $60 Variable cost per unit, year 1 $42 Life expectancy (years) Salvage value SO Depreciation Straight-line Tax rate 37% Real discount rate 10.0% Inflation rate 0.0% 8 a. Prepare a spreadsheet to estimate the project's annual after-tax cash flows. b. Calculate the investment's internal rate of return and its net present value assuming zero inflation. How do the internal rate of return and net present value change when you assume an inflation rate of 8 percent per year in price and variable cost per unit? How do you explain the fact that inflation causes the internal rate of return to increase and the NPV to decrease? d. e. Does inflation make this investment more attractive or less attractive? Why
