To find the number of cups of pomegranate juice needed to add to 20 cups of orange juice, we need to create a proportion using the given information in the table.
The proportion can be set up as:
5 cups of orange juice / 3 cups of pomegranate juice = 20 cups of orange juice / x cups of pomegranate juice
To solve for x, we can cross multiply and then divide:
5x = 20 * 3
5x = 60
x = 60 / 5
x = 12
So, Azeriah should add 12 cups of pomegranate juice to 20 cups of orange juice.
