The government expenditure is $20 billion.
To find the answer, we have to know about the Gross Domestic Product.
Using the output approach, the gross domestic product is determined as follows:
[tex]GDP=C+I_g+G+X_n[/tex]
Where: C is conception, Ig is the gross investment, G is government expenditure, and Xn is the net exports.
[tex]G=GDP-C-I_g-X_n\\G=100-60-30+10=20 billion-dollers.[/tex]
Thus, we can conclude that, the government expenditure is $20 billion.
