Consider the following projects:

Cash Flows ($)
Project	C0	C1
D	11,800	23,600
E	21,800	38,150

Assume that the projects are mutually exclusive and that the opportunity cost of capital is 9%.

a. Calculate the profitability index for each project. (Do not round intermediate calculations. Round your answers to 2 decimal places.)

Project	Profitability Index
D
E

b-1. Calculate the profitability-index using the incremental cash flows. (Do not round intermediate calculations. Round your answer to 2 decimal places.)
