Answer:
$48,398.58
Step-by-step explanation:
In 2010, the United States population was about 281 million people. So all we need to do is do 13,600,000,000,000 ÷ 281,000,000, then you get 48,398.58
So if we were to simply divide the national debt of the United States in 2010 by the population at that time, each person would have had to contribute about $48,398.58 to pay it off.
