Britney Javelin Company is considering two investments, both of which cost $28.000 . The cash flows are as follows. Use Apgentis B and Appendixi a. Calculate the payback period for project A and project B. (Round the final answers to 2 decimal places) b-1. Calculate the NPV for project A and project B Assume a cost of copital of 9 percent (Round "PV Factor" to 3 decimal places. Round the intermediate and final answers to the nearest whole dollar.) b-2. Which of the two projects should be chosen based on the NPV method? Project B Project A Both c. Should a firm normally have more confidence in answer derived based on NPV method or Payback method? NPV method Pay back method b-1. Caiculate the NPV for project A and project B. Assume a cost of capital of 9 percent (Round "PV Factor' to 3 decimal piaces. Round the intermediate and final answers to the nearest whole dollar.) b-2. Which of the two projects should be chosen based on the NPV method? Project B Project A Both c. Should a firm normalty have more confidence in answer derived based on NPV method or Paybock method? NPV method Poy back method .
