In a recent year, the number of $1 bills in circulation in the U.S. was about 7 billion. If the number of $10 bills was 20% of the number of $1 bills, about how many $10 bills were in circulation?

Answer by Guest

To find the answer, you should find 20% of 7 billion, so here's the formula:
7,000,000,000 * 0.5 
=3,500,000,000 $10 bills in circulation
