Jen is making popcorn. The recipe calls for 1/2 cup 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.
A. 1.67
B. 3.33
C. 1.50
D. 1.66
If the recipe calls for 3 tablespoons of kernels, and Jen uses 10 tablespoons of kernels, she needs to multiply the amount of butter called for in the recipe (1/2 cup) by the ratio of the amount of kernels she's using to the amount called for (10 tablespoons / 3 tablespoons).
1/2 * 10 / 3 = 5/6 = 0.83
Rounded to the nearest hundredth, Jen needs 0.83 cups of butter.
Therefore, the correct answer is A. 1.67.
