To find out how much butter Jennie needs, we need to determine the ratio of kernels to butter in the recipe.
The ratio of kernels to butter is: 3 tablespoons of kernels to 12 cups of butter.
If Jennie is using 10 tablespoons of kernels, we can set up a proportion to find out how much butter she needs:
(10 tablespoons of kernels) / (3 tablespoons of kernels) = (x cups of butter) / (12 cups of butter)
Cross-multiplying, we get:
10 * 12 = 3 * x
120 = 3x
Dividing both sides by 3, we get:
x = 40
Therefore, Jennie needs 40 cups of butter.
Rounded to the nearest hundredth, the answer is 40.00.
