Lang Industrial Systems Company (LISC) is trying to decide between two different conveyor belt systems. System A costs $240,000, has a four-year life, and requires $75,000 in pretax annual operating costs. System B costs $340,000, has a six-year life, and requires $69,000 in pretax annual operating costs. Whichever project is chosen LISC always needs a conveyor belt system, when one wears out, it must be replaced. Assume the tax rate is 34 percent and the discount rate is 8 percent. Calculate the EAC for both conveyor belt systems. Which conveyor belt system should the firm choose? System B System A
