X-treme Vitamin Company is considering two investments, both of which cost $13,000. The cash flows are as follows: Year 1 Project A $15,000 8,000 6,000 Project B $13,000 7,000 11,000 0-1. Calculate the payback period for Project A and Project B. (Round your answers to 2 decimal places.) Project A Project B Payback Period year(s) year(s) 0-2. Which of the two projects should be chosen based on the payback method? Project A Project B b-1. Calculate the net present value for Project A and Project B. Assume a cost of capital of 9 percent (Do not round intermediate calculations and round your final answers to 2 decimal places.) Net Present Value Project A Project B b-1. Calculate the net present value for Project A and Project B. Assume a cost of capital of 9 percent (Do not round intermediate calculations and round your final answers to 2 decimal places.) Net Present Value Project A Project B b-2. Which of the two projects should be chosen based on the net present value method? Project B Project A c. Should a firm normally have more confidence in the payback method or the net present value method? Payback method Net present value method
