Final answer:
To find the total quarts needed for the recipe, add 1 1/2 quarts of sparkling water to 3/4 quarts of grape juice, resulting in 2 1/4 quarts. Option D is the correct answer.
Step-by-step explanation:
To find out how much liquid is needed to make the sparkling grape juice recipe, you need to add the amount of sparkling water and grape juice together. The recipe calls for one and a half quarts of sparkling water and 3/4 quarts of grape juice.
To solve this problem:
- Add the quarts of sparkling water (1 1/2 or 1.5 quarts) to the quarts of grape juice (3/4 or 0.75 quarts).
- 1.5 quarts + 0.75 quarts = 2.25 quarts
Therefore, the total amount of liquid needed for the recipe is 2 1/4 quarts, which corresponds to option D.
