Lang Industrial Systems Company (LISC) is trying to decide between two different conveyor belt systems. System A costs $268,000, has a four-year life, and requires $82,000 in pretax annual operating costs. System B costs $378,000, has a six-year life, and requires $76,000 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 35 percent and the discount rate is 10 percent.
