Consider the following projects: Cash Flows ($) Project CO C1 D -10,500 21, 900 m -20,500 35,875 Assume that the projects are mutually exclusive and that the opportunity cost of capital is 10%. a. Calculate the profitability index for each project. (Do not round intermediate calculations. Round your answers to 2 decimal places.) Project Profitability Index D F b-1. Calculate the profitability-index using the incremental cash flows. (Do not round intermediate calculations. Round your answer to 2 decimal places.) Profitability-index
