Suppose that by investing $20,000 in Machine A, a producer could increase his net cash flows as given below. Investing in $9,500 in Machine B, would also yield the net cash flows given below. Assuming a weighted average cost of capital of 15 percent, answer the following: Machine A Machine B CF = $(20,000) CF, = $(9,500) CF, - $6,500 CF - $5,500 CF, - $ 6,500 CF,- $5,500 CF, = $ 6,500 CF, - $5,500 CF, - $ 6,500 CF, = $ 6,500 a Using the Net Present Value (NPV) approach, evaluate (solve for NPV and indicate if you would invest or not) the investment in Machine A. b. Using the Net Present Value (NPV) approach, evaluate (solve for NPV and indicate if you would invest or not) the investment in Machine B. C. If the producer could invest in only one machine, use the Annuity Equivalents approach to determine which one should he invest in
