PS: I had 1.6483 for project A and 1.4921 for project B but those answers are incorrect. Please show how you did it so I can learn. Thanks.

The following are the cash flows of two projects: Year Project A Project B $ (250) $ (250) 1 130 150 2 130 150 3 130 150 130 4 If the opportunity cost of capital is 10%, what is the profitability index for each project? (Do not round intermediate calculations. Round your answers to 4 decimal places.)
