please help with part b of the question

Crockett Graphic Designs Inc. is considering two mutually exclusive projects. Both projects require an initial after-tax investment of $12,000 and are typical average-risk projects for the firm. Project A has an expected life of 2 years with after-tax cash inflows of $6,000 an $10,000 at the end of Years 1 and 2, respectively. Project B has an expected life of 4 years with after-tax cash inflows of $5,000 at the end of each of the next 4 years. The firm's WACC is 11%. a. If the projects cannot be repeated, which project should be selected if Crockett uses NPV as its criterion for project selection? Project should be selected. b. Assume that the projects can be repeatedand that there are no anticipated changes in the cash flows. Use the replacement chain analysis to determine the NPV of the project selected. Do not round intermediate calculations. Round your answer to the nearest cent. Since Project 's extended NPV =$ , it should be selected over Project with an NPV =$ c. Make the same assumptions as in part b. Using the equivalent annual annuity (EAA) method, what is the EAA of the project selected? Project should be selected
