Answer:
<em>The GDP Rounded to the answer to the nearest ten = $21 trillion</em>
Explanation:
What Is GDP?
<em>Gross Domestic Product (GDP) is the total monetary or market value of all the finished goods and services produced within a country's borders in a specific time period. As a broad measure of overall domestic production, it functions as a comprehensive scorecard of the country’s economic health. </em>
<em>Though GDP is usually calculated on an annual basis, it can be calculated on a quarterly basis as well.</em>
<em></em>
<em>Using the The Expenditure Method - Aggregate Demand (AD) the formula for GDP is: </em>
GDP = C + I + G + (Ex - Im),
where “C” equals spending by consumers,
“I” equals investment by businesses,
“G” equals government spending and
“(Ex - Im)” equals net exports, that is, the value of exports minus imports.
GDP =
C = 3.8 + 2.7 + 12.2 = $18.7 trillion
I = 2.1 + 0
GDP = 18.7 + 2.1 = <em>$20.8 trillion </em>
<em>GDP = $20.8 trillion </em>
