A pitcher holds 2 gallons of orange juice. The orange juice is made 20% concentrated juice and 80% water. How much water is used in the orange juice?

0.8 * 2 = 1.6 gallons

2 gallons = 16 cups

.8 x 16 = ?? cups

To find out how much water is used in the orange juice, we need to calculate 80% of the total volume of the orange juice.

Since the pitcher holds 2 gallons of orange juice, we can calculate it as follows:

80% of 2 gallons = (80/100) * 2 gallons = 1.6 gallons

Therefore, 1.6 gallons of water is used in the orange juice.
