Final answer:
The dollar value of GDP for Country A is calculated by adding consumption spending, business investment, and government purchases, and then subtracting the value of imports from that of exports. The calculation leads to a GDP value of $3,030 billion.
Step-by-step explanation:
To calculate the dollar value of GDP for Country A, you must consider all components of GDP following the formula:
GDP = C + I + G + (X - M)
Where:
C is consumption spending
' I ' is the business investment
G is government purchases
X is export sales
M is imports
Substituting the given values, we have:
GDP = $2,000 billion (C) + $50 billion (I) + $1,000 billion (G) + ($20 billion (X) - $40 billion (M))
This results in:
GDP = $2,000B + $50B + $1,000B + ($20B - $40B)
GDP = $2,000B + $50B + $1,000B + (-$20B)
GDP = $2,000B + $50B + $1,000B - $20B
GDP = $3,030 billion
So, the dollar value of GDP for Country A is $3,030 billion.
