Answer:
$526 billion
Step-by-step explanation:
If at the beginning of 2009, a government had a total debt of $540 billion dollars, and it ended 2009 with a $6 billion dollar budget surplus; then in 2010, its budget surplus reached $8 billion dollars. Then the level of total debt would be decreased because:
When a country runs a budget surplus it has a positive effect of reducing the government total debt level of the country.
Hence, the level of government debt will drop from $540 billion from the beginning of 2009 to $526 billion ($540 - $6 - $8) in 2010
