To solve this problem, you can set up a proportion.
The original recipe called for 3 tablespoons of kernels and 1/2 cup of butter. So, the ratio of tablespoons of kernels to cups of butter is 3:1/2.
If Jennie is using 10 tablespoons of kernels, you can set up a proportion to find out how much butter she needs.
3 tablespoons / 1/2 cup = 10 tablespoons / x cups
To solve for x, cross-multiply and divide:
3x = 10(1/2)
3x = 5
x = 5/3
Rounded to the nearest hundredth, Jennie needs approximately 1.67 cups of butter.
Therefore, the correct answer is 1.67.
