Answer:

$5630

Explanation:

You want the value of a $20,500 car after 3 years if it declines in value by 35% each year.

Exponential function

The exponential function describing the value can be written as ...

value = (initial value) × (1 + growth rate)^t

where the growth rate is the change per year, and t is in years.

Application

Here, the initial value is 20,500, and the growth rate is -35% per year. The function is ...

value = 20500×(1 -0.35)^t

After 3 years, the value is ...

value = 20500(0.65³) ≈ 5630

The resale value after 3 years is $5630.
