To find the price per quart, we first need to determine how many quarts are in 3 gallons.
1 gallon is equal to 4 quarts, so:
\[ 3 \text{ gallons} \times 4 \text{ quarts/gallon} = 12 \text{ quarts} \]
Next, we know that the total cost of the 3-gallon container is $27.12. To find the price per quart, we divide the total cost by the number of quarts:
\[ \text{Price per quart} = \frac{\text{Total cost}}{\text{Number of quarts}} = \frac{27.12}{12} \]
Now we calculate that:
\[ \frac{27.12}{12} = 2.26 \]
Therefore, the price per quart is $2.26.
