Answer:
$20,000
Explanation:
GDP is the market value of all final goods and
services produced within a country in a given period of time.
The GDP includes only the value of final goods, the value of manufactured automobile in this question, not the value of intermediate goods used in it, the windshield, tires, and others.
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.
