Lets see. Each year, the price is the 85% of the price of the previous year. This can only mean one thing: the function is exponential.
We have:
v(t)=25500*(0,85)x

Determine the value of the car, to the nearest dollar, when it is 8 years old.
v(8)=25500*(0,85)8=25500*0,2724905250390625=6948,50838849609375=~6949$
