7. value: 10.00 points Lang Industrial Systems Company (LISC) is trying to decide between two different conveyor belt systems. System A costs $208,000, has a four-year life, and requires $67,000 in pretax annual operating costs. System B costs $294,000, has a six-year life, and requires $61,000 in pretax annual operating costs. Both systems are to be depreciated straight-line to zero over their lives and will have zero salvage value. Whichever project is chosen, it will not be replaced when it wears out. The tax rate is 34 percent and the discount rate is 8 percent. Calculate the NPV 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.) NPV System A System B Which conveyor belt system should the firm choose?

System A costs $212,000, has a four-year life, and requires $68,000 in pretax annual operating costs. System B costs $300,000, has a six-year life, and requires $62,000 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. (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? System B System A
