Shanice bought the car for $28,430. The value of the car is predicted to depreciate to $13,590 after 5 years.

1. If Shanice keeps the car for an additional 3 years (8 years total), predict the value of the car at the end of those 3 additional years, assuming the value continues decreasing exponentially at the same rate? $
2. The average maintenance costs on the car are expected to be $350 the year it is purchased and increase by $50 each year after that. Use this to predict the total maintenance costs during the 3 years after the loan is paid off.
