Peyton Manufacturing is trying to decide between two different conveyor belt systems. System A costs $$276,000,$ has a four$-$year life, and requires $$84,000$ in pretax annual operating costs. System B costs $$390,000,$ has a six$-$year life, and requires $$78,000$ in pretax annual operating costs. Both systems are to be depreciated straight$-$line to zero over their lives and will have zero salvage value. Whichever system is chosen, it will not be replaced when it wears out. The tax rate is $24$ percent and the discount rate is $8$ percent.

Calculate the NPV for both conveyor belt systems. $($A negative answer should be indicated by a minus sign. Do not round intermediate calculations and round your answers to $2$ decimal places, e$.$g$.,32\mathrm{.}16.)$
