3. (18 points) You are considering two different systems for pollution control. System I costs $965,000, has an eight year life, and has pre-tax operating costs of $7,280 per year. System II costs $570,000, has a five year life, and has pre-tax operating costs of $35,100 per year. For both systems use straight line depreciation and assume neither system has any salvage value. If your tax rate is 34% and your discount rate is 11%, which do you prefer? Show me with calculations
