Answer:
The correct answer is letter "B": $2 billion.
Step-by-step explanation:
Aggregate Expenditure or Gross Domestic Product (GDP) measures the productivity of a country given a certain period. It is calculated using the following formula:
GDP = C + I + G + NX
where:
- C = Consumption
- I = Investment
- G = Government Expenditures
- NX = Net Exports (exports - imports)
Net Exports are the difference between a country's exports and imports. It is calculated by subtracting the total exports value from the total imports value.
Therefore, in the case:
- $71 = $50 + $12 + $7 + NX
- $71 = $69 + NX
- $71 - $69 = NX
- NX = $2
Thus, Net Exports equal to $2 billion.
