First, convert Steph's 8 gallons into quarts:
8 gallons * 4 quarts/gallon = 32 quarts
Now, we can compare the amounts of water in quarts:
Steph has 32 quarts
Ryan has 30 quarts
To find the difference in pints, we'll subtract Ryan's amount from Steph's amount:
32 quarts - 30 quarts = 2 quarts
Finally, we'll convert the 2 quarts into pints:
2 quarts * 2 pints/quart = 4 pints
Therefore, Steph has 4 more pints of water than Ryan.
