Problem 12-14 Britney Javelin Company is considering two investments, both of which cost $14,000. The cash flows are as follows: Use Appendix B and Appendix D. Year 1 2 3 Project A $8,000 6,000 4,000 Project B $7,000 6,800 9,000 a. Calculate the payback period for project A and project B. (Round the final answers to 2 decimal places.) Payback period years Project A Project B years b-1. Calculate the NPV for project A and project B. Assume a cost of capital of 8 percent. (Round "PV Factor" to 3 decimal places. Round the intermediate and final answers to the nearest whole dollar.) Net present value Project A Project B $ b-2. Which of the two projects should be chosen based on the NPV method? Project A Project B O Both c. Should a firm normally have more confidence in answer derived based on NPV method or Payback method? O NPV method Pay back method
