Jennie is making popcorn. The recipe calls for 1/2 cup of butter, 3 tablespoons of kernels, and 1 teaspoon of salt. If she uses 10 tablespoons of kernels, how much butter does she need? Round your answer to the nearest hundredth

Answer 1

If the recipe calls for 3 tablespoons of kernels and she uses 10 tablespoons of kernels, she uses 10/3 = <<10/3=3.33>>3.33 times the amount of kernels required.
Since she needs 1/2 cup of butter in the recipe and she uses 3.33 times the amount of kernels required, she needs 3.33*1/2 = <<1/2*3.33=1.665>>1.665 cups of butter. Answer: \boxed{1.67}.
