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?
If 2 tablespoons of butter are required for every cup of popcorn kernels, then for 2 cups of popcorn kernels, we would need 2 x 2 = <<2*2=4>>4 tablespoons of butter. Therefore, 4 tablespoons of butter are required. The correct answer is 4.
