Lang Industrial Systems Company (LISC) is trying to decide between two different conveyor belt systems. System A costs $280,000, has a four-year life, and requires $85,000 in pretax annual operating costs. System B costs $396,000, has a six-year life, and requires $79,000 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 9 percent. Calculate the EAC for both conveyor belt systems. (Negative amounts should be indicated by a minus sign. Do not round intermediate calculations and round your answers to 2 decimal places. (e.g., 32.16)) EAC System A System B Which conveyor belt system should the firm choose? SystemB System A
