Lang Industrial Company (LISC) is trying to decide between two different conveyor belt systems. A cost $204,000 has a four-year life, and requires $66,000 in pretax annual operating cost. System B costs $288,000, has a six-year life, and requires $60,000 in pretax annual operating cost. 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 wars out. The tax rate is 35 percent and the discount rate is 10 percent.

Calculate the NPV for both conveyor belt system.
