The cash flows for three alternatives are as follows:

Year	A	B	C
0	-$500	-$600	-$900
1	-400	-300	0
2	200	350	200
3	250	300	200
4	300	250	200
5	350	200	200
6	400	100	200

a.) Based on payback period, which alternative should be selected?

b.) Using future worth analysis, and a 8% interest rate, determine which alternative should be selected.

c.) If the answers to a) and b) are not the same, explain why. If they are the same, then omit this part.

Clearly show all steps with formulas used to get to the correct answer. Microsoft Excel is optional.
