Letang Industrial Systems Company (LISC) is trying to decide between two different conveyor belt systems. System A costs $285,000, has a four-year life, and requires $89,000 in pretax annual operating costs. System B costs $365,000, has a six-year life, and requires $83,000 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 24 percent and the discount rate is 11 percent. Calculate the EAC for both conveyor belt systems.
