Question 1.

Question 2.

Compare two alternatives, A and B, on the basis of a present worth evaluation using i =14% per vear and a study period of 8 vears. The present worth of alternative A is $ and that of alternative B is $ Alternative ( is selected. 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 17% per year, which alternative has the lower present worth? The present worth for the DDM method is \$ The present worth for the LS method is \$ The: :method is selected
