To find out how much butter Jennie needs, we need to compare the amount of kernels she is using with the original recipe.
The original recipe calls for 3 tablespoons of kernels and 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.
3 tablespoons of kernels / 12 cups of butter = 10 tablespoons of kernels / x cups of butter
Cross multiplying, we get:
3x = 10 * 12
3x = 120
x = 40
Therefore, Jennie needs approximately 40 cups of butter.
Rounding to the nearest hundredth, the answer is 40.00.
