Jennie is making popcorn. The recipe calls for 12 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

To calculate the amount of butter Jennie needs, we can set up a proportion.

We know that 3 tablespoons of kernels require 12 cups of butter.

Let's represent the unknown amount of butter Jennie needs as x cups:

3 tablespoons / 12 cups = 10 tablespoons / x cups

To find x, we can cross-multiply and solve for x:

3x = 10 * 12
3x = 120
x = 120 / 3
x = 40

Therefore, Jennie needs 40 cups of butter. Rounding to the nearest hundredth, the answer is 40.00 cups.
