A recipe for making popcorn requires 2 tablespoons of butter for every cup of popcorn kernels. At this rate, how much butter is required if 2 cups of popcorn kernels are used?

A. 12 tablespoons
B. 10 tablespoons
C. 6 tablespoons
D. 4 tablespoons

Answer :

Final answer:

When 2 cups of popcorn kernels are used, 4 tablespoons of butter are required.

Explanation:

To find out how much butter is required when 2 cups of popcorn kernels are used, we need to use the given rate of 2 tablespoons of butter for every 1 cup of popcorn kernels. Since we have 2 cups of popcorn kernels, we can set up a proportion to solve for the amount of butter:

2 cups of popcorn kernels / 1 cup of popcorn kernels = x tablespoons of butter / 2 tablespoons of butter

Cross multiplying, we get 2x = 4, which means x = 4/2. Therefore, 4 tablespoons of butter are required when 2 cups of popcorn kernels are used.
