Data for two mutually exclusive alternatives at an interest rate of 7% are given below.

	Alternative A	Alternative B
Initial Cost	$4,000	$3,000
Annual Benefit ( Begin at end of year 1)	$1,000	$600
Annual Cost ( Begin at end of year 1)	$300	$100
Salvage Value	$500	$0
Useful Life (years)	5	10

Assume that you can replace Alternative A after 5 years. Therefore, you must consider the analysis period to be 10 years.

What is the net present worth (to the closest penny) for Alternative A?
