Consider the investment projects given in the table below. Assume that MARR=13% in the following questions.
	Net Cash Flow
n	Project 1	Project 2	Project 3
0	($9,000)	($6,500)	($2,500)
1	$10,500	$13,000	$10,000
2	$10,500	$28,000	($10,000)
3	-	($43,000)	-
a) compute i* for each investment, identify all of them
b) compute IRR(true) for the project
c) compute the MIRR at MARR=13%
d) determine the acceptability of each investment
