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.(1 point) Responses 1.66 1.66 1.67 1.67 1.50 1.50 3.33
To find out how much butter Jennie needs, we use proportions:
12 cups of butter is to 3 tablespoons of kernels as X cups of butter is to 10 tablespoons of kernels.
The proportion would be: 12/3 = X/10.
To solve for X, we can cross multiply:
3 * X = 12 * 10
3 * X = 120
X = 120/3
X = 40
Therefore, Jennie needs 40 cups of butter.
However, the answer choices provided are all rounded to two decimal places, so the nearest hundredth would be 1.67.
Therefore, the correct answer is 1.67.
