Answer:
$20,000
Explanation:
GDP is the market value of <u>all final goods and
</u>
<u>services</u> produced within a country in a given period of time.
The GDP includes only the value of final goods, <em>the value of manufactured automobile in this question</em>, not the value of intermediate goods used in it, <em>the windshield, tires, and others.</em>
Reason: The price of intermediate goods (windshield, tires, CD player) is already included in the final price of $20,000.
Hence, GDP discourage to include these intermediate goods value as it will lead to double counting given that they're already included in final price of $20,000.
