Answer:
A net capital inflow of $10 billion.
Step-by-step explanation:
Given that,
Government spending = $30 billion,
Consumption = $70 billion,
Taxes = $20 billion,
GDP = $100 billion
Investment spending = $10 billion
Y = Consumption + Investment spending + Government spending
= (Consumption - Taxes) + $10 billion + $30 billion
= ($70 billion - $20 billion) + $10 billion + $30 billion
= $50 billion + $10 billion + $30 billion
= $90 billion
As the amount of GDP is greater than the value of income (Y). Hence, there is a net inflow of capital:
= GDP - Y
= $100 billion - $90 billion
= $10 billion
