The mayor of Trenton is considering the purchase of a new computer system for the city's tax department. The system costs $81,000 and has an expected life of five years. The mayor estimates the following savings will result if the system is purchased:

Year		Savings
1		$	26,000
2			25,000
3			30,000
4			21,000
5			10,000

What can be said about the computer system's internal rate of return if the net present value at 13% is positive? Trenton uses a 11% discount rate for capital-budgeting decisions.
