We have 9 gallon of juice and each gallon of juice is made up of 128 ounces. To convert the 9 gallons of juice to ounces, we have: 9 * 128 = 1152 ounces. To calculate the amount of 8 ounces cups that can be obtained from 1152 ounces, we have: 1152 / 8 = 144.
Therefore, the number of 8 ounces cup that can be found in 9 gallons of juice is 144.
