Rust Industrial Systems Company is trying to decide between two different conveyor belt systems. System A costs $$320,000,$ has a four$-$year life, and requires $$117,000$ in pretax annual operating costs. System B costs $$400,000,$ has a six$-$year life, and requires $$111,000$ in pretax annual operating costs. Suppose the company always needs a conveyor belt system; when one wears out, it must be replaced. Assume the tax rate is $21$ percent and the discount rate is $10$ percent. Calculate the EAC 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$.,32\mathrm{.}16.)$
