Final answer:
The gross output for the economy is $140 billion, which is the sum of resource extraction ($20 billion), production ($50 billion), and distribution activities ($70 billion). For the reference information about Country A, the Gross Domestic Product (GDP) equals $3,030 billion.
Step-by-step explanation:
The student has asked for the gross output for an economy based on various economic activities. Gross output can be understood as the sum of the dollar value of resource extraction, production activity, and distribution activity. Here, the gross output calculation would be as follows:
- Resource extraction activity = $20 billion
- Production activity = $50 billion
- Distribution activity = $70 billion
Adding these up gives:
$20 billion + $50 billion + $70 billion = $140 billion
This would make option B, $140 billion, the correct answer for the gross output.
In the provided reference information about Country A, the Gross Domestic Product (GDP) is calculated by summing up consumption, investment, government spending, and net exports which is exports minus imports (C+I+G+(X-M)). Applying this formula:
GDP = $2,000 billion + $50 billion + $1,000 billion + ($20 billion - $40 billion)
GDP = $2,000 billion + $50 billion + $1,000 billion + (-$20 billion)
GDP = $3,030 billion
