This equation is known as the equation for exponential growth/decay:
Since the car is worth no more than $1,900 when bought, we can rewrite the above equation as:
<u>a is the initial value, and b is the growth factor, x is the </u><u>amount of</u><u> time that passes.
</u>So, we can plug in all that information (it's negative because the car's value goes <em>down</em>):
<u>
</u>That's your final answer^.<u>
