Answer: $1400 / year

Explanation:

Let's start by finding the difference in the new car and the price 8 years later:

$19200 - $8000 = $11200

This means the car depreciated by $11200 over 8 years. We divide this by the 8 years:

$11200 / 8 years = $1400.

This means the car changed by an average of $1400 each year.
