Tim Smunt has been asked to evaluate two machines. After some investigation, he determines that they have the costs shown in the following table:

	Machine A		Machine B
Original Cost	$10,000		$20,000
Labor per year	$2,400		$4,000
Maintenance per year	$4,300		$800
Salvage value	$2,000		$7,000

He is told to assume that:

1. The life of each machine is 3 years.

2. The company thinks it knows how to make 14% on investments no more risky than this one.

3. Labor and maintenance are paid at the end of the year.

The NPV for Machine A=

The NPV for Machine B=
