Consider three alternatives below, each with a 5-year useful life. The MARR is 10 %. You must solve this problem using benefit-cost ratio analysis.

Alternatives	Alpha	Beta	Gamma
Cost	$600	$530	$200
Uniform Annual Benefit	$158.3	$138.7	$58.3

Answer (IRR of Alpha to two decimal places, e.g. 8.33%) ______________ .

Answer (IRR of Beta to two decimal places, e.g. 8.33%) _______________ .

Answer (IRR of Gamma to two decimal places, e.g. 8.33%) _____________

One of the above three alternative's IRRs will not meet the MARR.

Answer (incremental B-C ratio between the other two alternatives to 3 decimal places) ____________

Answer (which alternative should be selected and why) ____________________________________
