The answer depends on how much is served to each person.
7 1/2 gallons
I would get instant tea and a big pot. Put in water and stir in tea until it is the strength you want. If you want something a bit different add blueberry juice, cranberry juice to the tea. This is called Boston tea and is very refreshing. Stir in ice for a cool drink.
You would need 7.5 gallons to get 120 8 ounce servings.
81.25 gallons....serving each person 8 oz of coffee.
About 4 gallons, allowing for an 8 oz. serving, One gallon will serve about 16 people.
The number of people is (640) divided by (the number of ounces that each person consumes) .
About 5 or 6 bucks.
