Carla Vista Mills management is evaluating two alternative heating systems. Costs and projected energy savings are given in the following table. The firm uses 11.50 percent to discount such project cash flows.

Year		System 100		System 200
0		$1,718,600		$1,416,700
1		270,810		598,700
2		504,930		523,800
3		800,740		541,300
4		737,300		300,100

What is the NPV of both systems? And Which one should be chosen? (Enter negative amounts using negative sign, e.g. -45.25. Do not round discount factors and intermediate calculations. Round final answers to 0 decimal places, e.g. 5,275.)
