A machine will reduce labor costs by $3,000 per month. It has a lifespan of 2 years, and no salvage value. Maintenance costs start at $50 per month, and increase by $50 each month. (So for months 1,2,3,4 costs are $50, $100, $150, $200.) Assuming a nominal annual discount rate of 6%, what’s the most you should pay for such a machine? (Neglect tax and depreciation.)
