Consider the following two mutually exclusive projects:

  

Year	Cash Flow (A)				Cash Flow (B)
0	$	-350,000			$	-50,000
1		45,000				24,000
2		65,000				22,000
3		65,000				19,500
4		440,000				14,600
Whichever project you choose, if any, you require a 15 percent return on your investment.    a. What is the payback period for each project? b. What is the discounted payback period for each project? c. What is the profitability index for each project?
