The snack bar a the soccer field is charging $12 for 9 hamburgers. At that rate how many hamburgers could you get for $20?

To determine how many hamburgers you can get for $20 at the given rate, we can use a proportion. The rate is $12 for 9 hamburgers, so we can set up the following proportion:

\[
\frac{12}{9} = \frac{20}{x}
\]

Where $ x $ is the number of hamburgers you can get for $20. Now, solve for $ x $:

1. Cross-multiply to solve for $ x $:

\[
12x = 9 \times 20
\]

2. Calculate the right-hand side:

\[
12x = 180
\]

3. Divide both sides by 12 to isolate $ x $:

\[
x = \frac{180}{12} = 15
\]

So, for $20, you can get **15 hamburgers** at that rate.

Here are five related questions:
1. How much would it cost to buy 30 hamburgers at this rate?
2. What is the price per hamburger at the current rate?
3. If you only had $5, how many hamburgers could you buy?
4. How much would it cost for 50 hamburgers at the same rate?
5. If the price was $15 for 9 hamburgers, how many could you get for $20?

**Tip:** When solving rate problems, setting up proportions can be a powerful method to find unknown quantities.
