Two methods can be used to produce expansion anchors. Method A costs $$65000$initially and will have a $$11000$ salvage value after $3$ years. The operating cost with this$$method will be $$21000$ in year $1,$ increasing by $$2200$ each year. Method B will have a$$first cost of $$101000,$ an operating cost of $$7000$ in year $1,$ increasing by $$7000$ each year,$$and a $$31000$ salvage value after its $3-$year life. At an interest rate of $9\mathrm{.}00\%$ per year, which$$method should be used on the basis of a present worth analysis?$($Include a minus sign if necessary.$)$

The present worth for method A is $ $.$

The present worth for method B$$is $ $.$
