Part A ending answer: 3 cups.
1/4 of a gallon=4 cups
If I understand this correctly, there was a total of 7 cups before it was poured, adding the original answer to this one.
7 cups would equal .43 gallons, a bit less than half a gallon. If that's so, then .43 would equal 43 percent, and 43% of 128 fluid ounces would be 55.04 fluid ounces. Now the further solution, with more numbers past the decimal, it would be equal to approximately 56.
Therefore, my answer, if I understood correctly, would be 56.
