The equipment will cost $500,000 and is expected to last for 8 years. The engineer has the following information concerning the savings and salvage value estimates and the projected probabilities. Determine the NPW if Green Golfs MARR is 6%.

	P = .20	P = .50	P = .25	P = .05
Savings per year	$65,000	$82,000	$90,000	$105,000
Salvage value	40,000	55,000	65,000	75,000
