Answer:
The formula to calculate the Budget Balance is
Government Income - Government Expenditure
in this case
$1.05 billion - $1.06 billion = - 0.01 billion or - $100 million
Step-by-step explanation:
A budget balance is reached when a government expenditures are equal to it's income.
In this case, since the country's only source of income it is slightly less than than what is required to run the government, it has a budget deficient.
Since the country does not export or trade with outside countries, the government will need to take out a loan to make up for this deficient.
