The snack bar at the soccer field is charging 12$ for 9 hamburgers. At that rate, how many hamburgers could u get for 20$

To find how many hamburgers you could get for $20, we can set up a proportion based on the price per hamburger.

From the problem:
- The price for 9 hamburgers is $12.

Let's set up the proportion:
\[
\frac{9 \text{ hamburgers}}{12 \text{ dollars}} = \frac{x \text{ hamburgers}}{20 \text{ dollars}}
\]
Now, we can solve for $ x $ by cross-multiplying:
\[
9 \times 20 = 12 \times x
\]
\[
180 = 12x
\]
Now, divide both sides by 12:
\[
x = \frac{180}{12} = 15
\]

So, for $20, you can get 15 hamburgers.
