Need help on calculating the Incremental IRR. Please show your work.

Consider the following cash flows of two mutually exclusive projects for Tokyo Rubber Company. Assume the discount rate for both projects is 6 percent. Solvent Year Dry Prepreg Prepreg 0 1,880,000 840,000 1 1,118,000 465,000 936,000 780,000 3 768,000 426,000 a. What is the payback period for both projects? (Do not round intermediate calculations. Round your answers to 2 decimal places, e.g., 32.16.) Dry Prepeg Solvent Prepeg 1.81 years 1.48 years b. What is the NPV for both projects? (Do not round intermediate calculations. Round your answers to 2 decimal places, e.g., 32.16.) Dry Prepeg Solvent Prepeg $ $ 652,581.26 650,554.28 b. What is the NPV for both projects? (Do not round intermediate calculations. Round your answers to 2 decimal places, e.g., 32.16.) Dry Prepeg Solvent Prepeg | $ $ 652,581.26 650,554.28 c. What is the IRR for both projects?
