Question

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.
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.
