Since 3 boxes of gelatin require 9 oz of powder and 6 cups of water, we can find the ratio of powder to gelatin by dividing the total amount of powder by the total number of boxes: 9 oz / 3 boxes = 3 oz/box.
Similarly, we can find the ratio of water to gelatin by dividing the total amount of water by the total number of boxes: 6 cups / 3 boxes = 2 cups/box.
Therefore, to make 7 boxes of gelatin, Jeff will need 3 oz/box * 7 boxes = 21 oz of powder and 2 cups/box * 7 boxes = 14 cups of water.
The correct answer is Jeff will use 21 oz of powder and 14 cups of water.
