Please solve this problem out by hand. My financial calculator broke and I need to understand the concept of IRR better and how to solve it manually. Thank you in advance for your help!

Consider the following cash flows on two mutually exclusive projects for the Bahamas Recreation Corporation (BRC) Both projects require an annual return of 17 percent Deepwater New Submarine Year Fishing Ride 0 $1,005,000-$1,960,000 425,000 554,000 475,000 1,010,000 855,000 860,000 a-1. Compute the IRR for both projects. (Do not round intermediate calculations. Enter your answers as a percent rounded to 2 decimal places, e.g., 32.16.) IRR Deepwater Fishing Submarine Ride a-2. Based on the IRR, which project should you choose? Submarine Ride Deepwater Fishing b-1. Calculate the incremental IRR for the cash flows. (Do not round intermediate calculations. Enter your answer as a percent rounded to 2 decimal places, e.g., 32.16.) Incremental IRR b-2. Based on the incremental IRR, which project should you choose? Deepwater Fishing Submarine Ride c-1. Compute the NPV for both projects. (Do not round intermediate calculations. Round your answers to 2 decimal places, e.g., 32.16.) NPV Deepwater Fishing Submarine Ride c-2. Based on the NPV, which project should you choose? Deepwater Fishing Submarine Ride c-3. Is the NPV decision consistent with the incremental IRR rule? Yes No
