An emission control system for a new car costs $800 and reduces NO_x emissions from 0.4 g/mile to 0.23 g/mile. Assume the car is driven 10000 miles per year, and the life of the emissions control system is 11 years with zero scrap value.
What is the annualized cost of this system in dollars per year if the discount rate (interest rate) is 5% per year?
What is the cost per 100 miles driven?
What is the cost per metric ton of NOx removed?
