Consider this data with MARR = 10%.
			System A	System B
		Initial Cost	65000	85000
		Service Life yrs	5	9
		Annual Revenue	19000	19000
1. Why would AW (Annual Worth) be a convenient method here?
2. In order to use the AW approach there is something which must be planned for the future; what is it?
3. What is the AW of each for the given MARR?
4. Based on the result of 3 which is the better investment?
5. Determine if the internal rate of return for System A is higher than 15%.
