So obviously I answered the questions, but I just realized I wasn't using my TI-84 Plus CE calculator to its full potential by using the npv function. Is there a way to answer this using the function in the calculator? If so, what would you input into the calculator?

McKnight Company is considering two different, mutually exclusive capital expenditure proposals. Project A will cost $448,000, has an expected useful life of 11 years, a salvage value of zero, and is expected to increase net annual cash flows by $73,100. Project B will cost $299,000, has an expected useful life of 11 years, a salvage value of zero, and is expected to increase net annual cash flows by $50,300. A discount rate of 9% is appropriate for both projects. Click here to view the factor table. Compute the net present value and profitability index of each project. (If the net present value is negative, use either a negative sign preceding the number eg -45 or parentheses eg (45). Round present value answers to 0 decimal places, e.g. 125 and profitability index answers to 2 decimal places, e.g. 15.25. For calculation purposes, use 5 decimal places as displayed in the factor table provided.) Net present value - Project A $ 49459 Profitability index - Project A 1.11 Net present value - Project B 43301 Profitability index - Project B 1.14
