Decision D$6,$ which has three possible choices $($X$,$ Y$,$ or Z$),$ must be made in year $3$ of a $6-$year study period in order to maximize E$($PW$).$ Using an MARR of $13\%$ per year, the investment required in year $3,$ and the estimated cash flows for years $4$ through $6,$ determine which decision should be made in year $3.$

The present worth of X is $ $\_\_\_\_.$

The present worth of Y is $ $\_\_\_\_.$

The present worth of Z is $ $\_\_\_\_.$
