Question

The U.S. public debt as of October 2010 was $9.06 × 1012. What was the average U.S. public debt per American if the population in 2010 was 3.08 × 108 people? Round the multiplier to the nearest hundredth.

Answer 1

The average U.S. public debt per American is approximately $29,400

Solution-

Given in the question,

U.S public debt as of October 2010 = $9.06×10¹²

Population of U.S in 2010 = 3.08×10⁸

We have to calculate the average U.S. public debt per American,

`\text{Average debt per American}=\frac{\text{Total debt}}{\text{Population}}\\\\=(9.06* 10^(12))/(3.08* 10^8)\\\\=2.9415* 10^((12-8))\\\\=2.9415* 10^4 \approx 2.94* 10^4=29,400`

Therefore, the average U.S. public debt per American is $29,400 (after rounding off)
