You have decided to buy a car this year at a price of $18,000. You're planning to take out a loan for the full price of the vehicle at an interest rate of .5% per month. For the first two years (24 months), you decide to repay $600 per month. How much will you have to pay each month for the remainder of the three-year loan (12 months remain) to exactly pay off the car in full at the end of the three-year term?
