Suppose a 4-year project has an initial cost of -40,000, annual benefit is 8000/year and the salvage value is 5000. Assume an interest rate of 8%, what is the NPV of this project? A. -9550 B. -13503 C. -10499 D. -9828 The cash flows for three different alternatives are given in table below. MARR = 10%. Delta RoR for the first increment (Alt. C-Alt. A) is ___. A. 10.12% B. 9.38% C. 11.85% D. 11.00% Delta RoR for the second increment is ___. A. 10.12% B. 9.38% C. 8.94% D. 9.87% The best alternative for a MARR of 10% using the incremental rate of return analysis is ___. A. Alt. C B. Alt. A C. Alt. B D. Do-nothing Given the data for three different alternatives in the table below, determine the best alternative using the incremental rate of return (Delta RoR) analysis. MARR = 9%. The best alternative is ___. A. Alt. A or Alt. B B. Alt. A C. Alt. C D. Alt. B
