Carly is running the punch stand at her school fair. She was given 2 gallons of pineapple juice, 17 pints of watermelon juice, 9 cups of strawberry juice, 1 gallon of blueberry juice, and 1.5 gallons of mango juice. A cup of punch is 8 fluid ounces. The punch recipe calls for a half gallon of each juice mixed together. How many cups of punch can Carly make with the materials given?
