The mayor of Trenton is considering the purchase of a new computer system for the city's tax department. The system costs $80,000 and has an expected life of five years. The mayor estimates the following savings will result if the system is purchased:

Year or Period		Savings				PV of $1 at 8%				PV of an ordinary annuity at 8%
1		$	25,000				0.926				0.926
2			30,000				0.857				1.783

5			17,000				0.681				3.993
