Question 4 (25 points): Two mutually exclusive investments have the following cash flows: Project A: CF I=1,300 ... L=$5,000 0 10 C=-5,000 1=1,000 1=1,100 1=1,200 1=1,300...1=1,300 Year 2 3 5-9 C: Cost, I: Income (I=1,300 in periods 4 through 10), L: Salvage Value Project B: CF I=1,300 ... ... L=$7,000 C=-7,000 1=1,300 1=1,300 1=1,300 1=1,300 1=1,300 2 3 5-9 C: Cost, I: Income (I=1,300 in periods 1 through 10), L: Salvage Value Year 0 4 10 The minimum rate of return is 10% (i* = 10%) for the first five years and 12% (i* =12%) for the last five years. Using NPV analysis, determine which investment is economically preferable
