Eads Industrial Systems Company (EISC) is trying to decide between two different conveyor belt systems. System A costs $538,000, has a 4-year life, and requires $133,000 in pretax annual operating costs. System B costs $630,000, has a five-year life, and requires $102,000 in pretax annual operating costs. Both systems are depreciated straight-line to zero over their lives and will e a salvage value of zero. Whichever system is chosen, it will not be replaced when it wears out. The tax and discount rates are 34% and 16%, respectively
