Here are the expected cash flows for three projects: Cash Flows (dollars Project Year0 -6,200 +1.300 +1.300 +3,600 -2,200 -6,200 +1,300 +1.300 +3,600 +5,600 0 +2.200 +2,600 +3,600 a. What is the payback period on each of the projects? Project b. If you use a cutoff period of 2 years, which projects would you accept? O Project A O Project B O ProjectC O Project A and Project B O Project B and Project C O Project A and Project C O Projects A, B, and O c. If you use a cutoff period of 3 years, which projects would you accept? O Project A O Project B O ProjectC O Project A and Project B O Project B and Project C O Project A and Project C O Projects A, B, and O d-1 lf the opportunity cost of capital is 10%, calculate the NPV for projects A, B, and C. (Negative amounts should be indicated by a minus sign. Do not round intermediate calculations. Round your answers to 2 decimal places.) 8
