Todd bought g boxes of granola bars. There are 12 granola bars in each box. Write an expression that shows how many granola bars Todd bought.

To find the total number of granola bars Todd bought, you can multiply the number of boxes (g) by the number of granola bars in each box (12). The expression is:

\[ 12g \]

This means Todd bought \( 12g \) granola bars in total.
