Final answer:
The dollar value of GDP can be calculated by adding up the components of GDP: consumption spending (C), investment (I), government purchases (G), and net exports (X - M). In this case, the dollar value of GDP is $3,030 billion.
Step-by-step explanation:
The dollar value of GDP can be calculated by adding up the components of GDP: consumption spending (C), investment (I), government purchases (G), and net exports (X - M).
In this case, the consumption spending is $2,000 billion, investment is $50 billion, government purchases are $1,000 billion, and net exports are the difference between export sales ($20 billion) and imports ($40 billion).
So, the dollar value of GDP is $2,000 billion + $50 billion + $1,000 billion + ($20 billion - $40 billion) = $3,030 billion.
