Given the following attributes of an investment project with a five-year life: investment outlay, year 0, $5,000; after-tax cash inflows, year 1, $800; year 2, $900; year 3, $1,500; year 4, $1,800; and year 5, $3,200. (a) Use the built-in NPV function of Excel to estimate the NPV of this project. Round your answer to the nearest whole dollar. Assume an after-tax discount rate of 12.0%. (b) Estimate the payback period, in years, for this project under the assumption that cash inflows occur evenly throughout the year. Round your answer to one 1 decimal place.
