Consider four mutually exclusive alternatives for an investment.

	A	B	C	D
Initial Cost	$3000	$1950	$5000	$3750
Uniform Annual Benefit	$1447	$959	$1700	$1651
Uniform Annual Costs	$145	$95	$189	$150
Life	4	4	4	4
Salvage	10% of first cost

Use a Rate of Return Analysis and Excel to solve for the following:

• Which alternative should be chosen using an MARR of 7%? Mathematical solution (5 points)
• Create a choice table from 0 20%. (5 points)
• Create a graphical solution to the problem indicating which alternative should be chosen for interest rates from 0 20%. (5 points). Make sure your graph has all proper labels.

There are no variables for this problem.
