What was the total income of everyone in the United States?

Question

In 2003 the population of the Unites States was 291 million people. The per-capita income was $31,459. What was the total income of everyone in the United States? Express you answer in scientific notation with the correct number of significant figures.

Answer 1

9.154569        .      10 (12 exponent)     would be the scientific notation for your question. My keyboard does not allow for         exponents .

 

 

The 12th power should be eleivated beside the 10 to be correctly written in scientific notation and the dot represents the multiplication of the two to get the correct notation.
