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 to the nearest hundredth.

Question

A. 1.67
B. 3.33
C. 1.66
D. 1.50

Answer 1

If the recipe calls for 3 tablespoons of kernels, and Jennie is using 10 tablespoons of kernels, that means she is using 10/3 = <<10/3=3.33>>3.33 times the amount of kernels called for in the recipe.
Since the recipe calls for 1/2 cup of butter, and Jennie is using 3.33 times the amount of kernels called for in the recipe, she will need 0.5 * 3.33 = <<0.5*3.33=1.665>>1.665 cups of butter.
Rounded to the nearest hundredth, Jennie will need 1.67 cups of butter.
Therefore, the answer is A. 1.67.
