Solution:
Given:
The value of a car after t - years will depreciate.
Hence, the equation given represents the value after depreciation over t-years.
To get the rate, we compare the equation with the depreciation formula.
Hence,
Therefore, the value of this car is decreasing at a rate of 6%. The purchase price of the car was $16,300.
