Ok, First put all the information into an equation. You have 20 gallons of water. You need 2 gallons for every 1 cup of energy drink mix.
It should look like this:
c=cups of energy drink mix
c=20/2
We are finding the number of cups (c) so we need to take the full amount of water (20 gallons) and dividing it by 2 because For every 1 cup, we need 2 Cups of drink mix.
Simply:
c=20/2 = c=10
you will need 10 cups of drink mixed to make 20 gallons of energy drink.
Answer:
10 cups.
