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.
