Answer
Figure This!
 

Answer:
Good Grape should have the strongest grape taste.

Complete Solution:
There are several ways to approach this problem:

Approach 1: One way is to determine how much concentrate each recipe uses for 1 cup of water. The one that uses the most concentrate should have the strongest grape taste.

RECIPE Cups of Concentrate per Recipe Cups of Water per Recipe

Ratio of Concentrate to Water

Ratio of Concentrate to 1 cup of Water
Jerry's Juice 2 3 2/3
Grapeade 5 8 5/8
Good Grape 3 4 3/4
Jane's Juice 4 7 4/7

Good Grape has the most concentrate (0.75) for 1 cup of water. It should have the strongest grape taste.

Approach 2: Another way is to find out how much water each recipe uses for 1 cup of concentrate. Here, the recipe that uses the least water should have the strongest grape taste.

RECIPE Cups of Concentrate per Recipe Cups of Water per Recipe

Ratio of Concentrate to Water

Ratio of 1 cup of Concentrate to Water
Jerry's Juice 2 3 2/3
Grapeade 5 8 5/8
Good Grape 3 4 3/4
Jane's Juice 4 7 4/7

Good Grape has the least amount of water, 1.3 cups, to 1 cup of concentrate, and so should have the most grape flavor.
