Peyton Manufacturing is trying to decide between two different conveyor belt systems. System A costs $244,000, has a four-year life, and requires $76,000 in pretax annual operating costs. System B costs $342,000, has a six-year life, and requires $70,000 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 21 percent and the discount rate is 10 percent.

Calculate the EAC for both conveyor belt systems.
