Each of the 223 million people put $10 back into circulation every year.
[tex]\sf 223,000,000\times 10=2,230,000,000[/tex]
So every year, this much money goes into circulation, and this is how much that goes into circulation the first year.
[tex]\sf 2,230,000,000+2,230,000,000=4,460,000,000[/tex]
This is how much that will be in circulation after 2 years.
[tex]\sf 4,460,000,000+2,230,000,000=6,690,000,000[/tex]
This is how much that will be in circulation after 3 years.
So we can create the table:
[tex] \sf\left[\begin{array}{cc}\sf Years&\sf Money&\sf 1&\sf 2,230,000,000\\\sf 2&\sf 4,460,000,000&\sf 3&\sf 6,690,000,000\end{array}\right] [/tex]
