es Rust Industrial Systems is trying to decide between two different conveyor belt systems. System A costs $204,000, has a four-year life, and requires $66,000 in pretax annual operating costs. System B costs $288,000, has a six-year life, and requires $60,000 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 24 percent and the discount rate is 10 percent. Calculate the EAC for both conveyor belt systems. Note: Your answers should be negative values and indicated by minus signs. Do not round intermediate calculations and round your answers to 2 decimal places, e.g., 32.16. System A System B
