Question 3: Assume that you have the following investment alternatives available: Alternative I Initial investment (now) of $ 500,000 with positive cash flows of $ 180,000 per year (starting at 1 year) for the next 4 years, i.e., a total of 4 flows of $ 180,000 Alternative II Initial investment (now) of $ 150,000 with cash flows equal to $ 150,000 (year 1), $ 50,000 (year 2) and $ 50,000 (year 3) A) Calculate the Payback Period of Alternative I. Assume that the flow occurs continuously during the respective period. (1 point) B) Write the equation that allows finding the IRR of Alternative II. If you can, Solve the equation in Excel or on your calculator. (1 point) C) If the discount rate is 10% per year, indicate which is the preferred alternative. Use Discounted cash flows but adjust for different durations. (2 points)
