Tanaka Industrial Systems Company is trying to decide between two different conveyor belt systems. System A costs $$275,000,$ has a $4-$year life, and requires $$81,000$ in pretax annual operating costs. System B costs $$355,000,$ has a $6-$year life, and requires $$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. 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 $9$ percent. Calculate the EAC for both conveyor belt systems.
