conversion factor: 1 pint = 0.5 quarts or 2 pint = 1 quart
multiplying both sides by 8
8(1 quart) = 8 (2 pints)
8 quarts = 16 pints
so she will need a total of 16 pints to fill the pot. she already has 1 so... 16 - 1 = 15 more pints.
and looking at the 1st conversion factor 1 pint = 0.5 quarts
15 (1 pint) = 15 (0.5 quart)
15 pints = 7.5 quarts
