Final answer:
You currently have 100 quarts when you combine 82 quarts of juice with 18 quarts of sparkling water, so no additional sparkling water is needed to reach the desired total of 100 quarts for the mixed drink.
Step-by-step explanation:
The question asked is, if you have 82 quarts of juice and 18 quarts of sparkling water, how much more sparkling water do you need to make a total of 100 quarts of the mixed drink? To solve this problem, we will start by adding the current amount of juice and sparkling water: 82 quarts of juice + 18 quarts of sparkling water = 100 quarts. This is the amount you currently have in total.
To find out how much more sparkling water you need, you should consider the total desired quantity of the mixed drink. You want to have 100 quarts in total. Since you already have 100 quarts when combining the juice and the sparkling water you currently have, there is no need for additional sparkling water to reach 100 quarts of mixed drink.
Therefore, you do not need any more sparkling water to achieve the desired total of 100 quarts of the mixed drink.
