Final answer:
The dollar value of GDP for Country A, calculated using the sum of consumption, investment, government purchases, and net exports (exports minus imports), is $3,030 billion.
Step-by-step explanation:
The Gross Domestic Product (GDP) is a measure that represents the dollar value of all goods and services produced over a specific time period within a country's borders. In the example provided, we can calculate GDP using the following formula:
GDP = Consumption + Investment + Government Purchases + (Exports - Imports)
Therefore, for Country A:
GDP = Consumption Spending ($2,000 billion) + Business Investment ($50 billion) + Government Purchases ($1,000 billion) + (Export Sales ($20 billion) - Imports ($40 billion))
GDP = $2,000 billion + $50 billion + $1,000 billion + ($20 billion - $40 billion)
GDP = $3,030 billion
So, the dollar value of GDP for Country A is $3,030 billion.
