Answer:
2 tsp
Explanation:
This is a ratio/ proportionality problem. The recipe calls for 2 1/2 cups of sugar, Jack uses 10 cups. Then 10/(2
) = 4, meaning he used 4 times the amount of sugar than in the original. Using that, just multiply
by 4 to get 4 times the vanilla of the og recipe, which equals 2 tsp.
