Question 11

Solve the problem. Express the answer in scientific notation to two decimals.
-The national debt of a small country is $ 6,710,000,000 and the population is 2,181,000. What is the amount of debt per person?

Accepted Answer

To find the amount of debt per person, divide the total debt by the population: $6,710,000,000 / 2,181,000 = $3,077.63. In scientific notation with two decimals, this is $3.08 × 10^3.
