Answer:
8 cups of sparkling water
Step-by-step explanation:
This is a ratio problem, the ratio is 2:4 because there are 4 cups of apple juice for every 2 cups of sparkling water, if there are 16 cups of apple juice, there will have to be 8 cups of sparkling water because if you do something to one part of the ratio, you have to do it to the other part too. you have to multiply 4 x 4 to get 16, so if you multiply 2 and 8, you get 16, which then makes the ratio equivalant and correct
