Dexcon Technologies, Inc., is evaluating two alternatives to produce its new plastic filament with tribological (i.e., low friction) properties for creating custom bearings for 3-D printers. The estimates associated with each alternative are shown below. Using a MARR of 16% per year, which alternative has the lower present worth?

Method	DDM	LS
First Cost	$-170,000	$-350,000
M&O Cost, per Year	$-65,000	$-40,000
Salvage Value	$4,000	$29,000
Life	2 years	4 years

The present worth for the DDM method is $ .

The present worth for the LS method is $ .
