Cory bring five 1 gallon jugs of juce to serve during parent night at his school. The paper cups he is using for drinks can hold 8 fluid ounces. How many drinks can Cory serve for parent night.

80 cups  

Step-by-step explanation:

Cory brings 5 one gallon jugs of juice to serve during parent night so we can also say that Cory brought 5 gallons of juice.

The cups he uses are 8 fluid ounces:

1 gallon = 128 fluid ounces

The amount of juice that he brought in fluid ounces is therefore:

= 128 * 5

= 640 fluid ounces

The number of drinks he can therefore serve is:

= 640/8

= 80 cups
