Hagar Industrial Systems Company $($HISC$)$ is trying to decide between two different conveyor belt

systems. System A costs $$290,000,$ has a four$-$year life, and requires $$85,000$ in pretax annual operating

costs. System B costs $$405,000,$ has a six$-$year life, and requires $$75,000$ 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. If the tax rate is $34$ percent and the

discount rate is $11$ percent, which system should the firm choose?
