Answer:
Step-by-step explanation:
Use the exponential function
where a is the initial value of the car, b is the rate of decay, and t is the time in years. For us, a = 18000, b = (1 - .15), so the model for this car is:
We can use this model now to find the value, v(t), of the car after 3 years has gone by (from 2006 to 2009 is 3 years):
and simplifying a bit:
v(t) = 18000(.614125) so
v(t) = 11054.25
Round however you need to.
