2. A used car can be kept for two more years and then sold for an estimated value of $3000, or it can be sold now for $7500. The average annual maintenance cost over the past 7 years has been $500 per year. However, if the car is kept for two more years, this cost is expected to be $1800 the first year and $2000 the second year. As an alternative, a new car can be purchased for $22,000 and be used for 4 years, after which it will be sold for $8000. The new car will be under warranty the first 4 years, and no extra maintenance cost will be incurred during those years. If the MARR is 15% per year, what is the better option? (13-46) 2.
