Answer:
7 quarts.
Explanation:
First, let's convert all the units to quarts. There are 2 pints in 1 quart, so 5 pints of orange sherbet is equivalent to 5/2 = 2.5 quarts. Similarly, 7 pints of vanilla ice cream is equivalent to 7/2 = 3.5 quarts. The recipe calls for 6 quarts of lemonade and 2.5 quarts of orange sherbet, for a total of 6 + 2.5 = 8.5 quarts of liquid. Since the punch bowl holds 4 gallons, which is equivalent to 4 * 4 = 16 quarts, Jasmine needs to add 16 - 8.5 = 7.5 quarts of ginger ale to the punch bowl. Since 1 quart is equivalent to 2 pints, Jasmine needs to add 7.5 * 2 = <<7.5*2=15>>15 pints of ginger ale to make one bowl of punch. Thus, the correct answer is 7 quarts.
