Rust Industrial Systems is trying to decide between two different conveyor belt systems. System A costs $$268,000,$ has a four$-$year life, and requires $$82,000$ in pretax annual operating costs. System B costs $$378,000,$ has a six$-$year life, and requires $$76,000$ in pretax annual operating costs. Both systems are to be depreciated straight$-$line to zero over their lives and will have zero salvage value. Suppose the company always needs a conveyor belt system; when one wears out, it must be replaced. Assume the tax rate is $22$ percent and the discount rate is $10$ percent. Calculate the EAC for both conveyor belt systems.
