Question

O 1.67

1.66

O 150

Answer 1

Jennie needs 3 tablespoons of kernels to make popcorn. If she uses 10 tablespoons of kernels, she will need to increase the proportion of other ingredients as well. Therefore, we need to find the ratio of butter to kernels from the original recipe and apply it to the new amount of kernels.

The original ratio of butter to kernels is 1/2 cup to 3 tablespoons. To find the amount of butter needed for 10 tablespoons of kernels, we can set up the following equation:

(1/2 / 3) = (x / 10)

Cross multiplying, we get:

3x = (1/2) * 10
3x = 5
x = 5/3

Rounded to the nearest hundredth, Jennie needs approximately 1.67 cups of butter when using 10 tablespoons of kernels. Therefore, the answer is O 1.67.
