Calculate the profitability index (PI) for each project. (Do not round discount factors. Round intermediate calculations to 2 decimal places, e.g. 15.25 and final answer to 4 decimal places, e.g. 1.2527.) The PI for project X is and the PI for project Y is Which project, or projects, should be accepted if you have unlimited funds to invest?
