Corey bought 
 
\[2\dfrac{1}2\] liters of paint for 
\[\$60\].
What was the cost per liter of paint?

To determine the cost per liter of paint, you can divide the total cost by the total number of liters.

Corey bought:

\[
2 \dfrac{1}{2} = \frac{5}{2} \text{ liters of paint}
\]

The total cost was $60.

To find the cost per liter:

\[
\text{Cost per liter} = \frac{60}{\frac{5}{2}} = 60 \times \frac{2}{5} = \frac{120}{5} = 24
\]

Thus, the cost per liter of paint is **$24**.

Here are five related questions for practice:
1. How would the cost change if Corey bought 3 liters for the same price?
2. What if Corey paid \$45 for 1.5 liters of paint?
3. If Corey needed 10 liters of paint, how much would it cost at this rate?
4. What would be the cost per liter if Corey got a discount and paid only \$50 for 2.5 liters?
5. How many liters could Corey buy with \$100 at this same cost per liter?

**Tip:** When dealing with mixed numbers, convert them into improper fractions for easier calculations.
