Rust Industrial Systems is trying to decide between two different conveyor belt systems. System A costs $248,000, has a four-year life, and requires $77,000 in pretax annual operating costs. System B costs $348,000, has a six-year life, and requires $71,000 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. 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. Which conveyor belt system should the fitm choose? System A System B
