Lang Industrial Systems Company (LISC) 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. Suppose LISC always needs a conveyor belt system; when one wears out, it must be replaced. Assume the tax rate is 30 percent and the discount rate is 9 percent.

Calculate the EAC for both conveyor belt systems.
