Amy and her sister are making lemonade for the school dance. their recipe makes 2 quarts of lemonade. if a serving of lemonade is one cup. how many gallons of lemonade will amy and her sister need to make in order to serve one serving of lemonade to 300 people?

It is 18.75 gallons.

Step-by-step explanation:

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

1.35x+1.08y=104.49.

3. solve the system of two equations:
