Answer:
9
Explanation:
There is a 1:8 ratio of sparkling soda to fruit punch, which means that for every one cup of sparkling soda, there will be eight cups, or two quarts (there are four cups in a quart), of fruit punch.
This means that if you had one quart of sparkling soda, you would need to add eight quarts of fruit punch- 1:8. 1 + 8 is 9, so in total, you would have 9 quarts of beverage.
