Lily bought 3 quarts of soda to make punch for a party. If she had 3 pints left over, how much did she use?

1 quart = 2 pints

3 * 2 = 6 pints

6 - 3 = 3 pints

To determine how much soda Lily used for the punch, we first need to understand the relationship between quarts and pints.

1 quart is equal to 2 pints.

Given that Lily has 3 quarts of soda, we can convert it to pints:

3 quarts * 2 pints/quart = 6 pints

This means Lily had a total of 6 pints of soda. Since she had 3 pints left over, we can calculate the amount she used for the punch:

Total soda used = Total soda - Soda left over
Total soda used = 6 pints - 3 pints
Total soda used = 3 pints

Lily used 3 pints of soda for the punch.
