Before the performance of the class play began, the sixth-graders filled big bowls with punch to serve during the intermissions.

They served 34 cups during the first intermission, so they made more by adding:

2 quarts of orange juice
2 quarts of ginger ale
2 12-ounce cans of fruit juice concentrate
6 12-ounce cans of water
4 ounces of pineapple juice

During the second intermission they served 7 quarts of punch they had poured into pitchers. They also served 18 cups of punch and 25 small glasses of punch, each equal to a half cup.

They ended up with 2 gallons of punch at the end of the performance.

How many gallons of punch were in the bowls at the beginning of the performance?
