To find out how much butter Jennie needs, we can use the proportion:
12 cups butter / 3 tablespoons kernels = x cups butter / 10 tablespoons kernels
Cross multiplying, we get:
10 tablespoons kernels * 12 cups butter = 3 tablespoons kernels * x cups butter
120 tablespoons kernels = 3 tablespoons kernels * x cups butter
Dividing both sides by 3 tablespoons kernels:
40 cups butter = x cups butter
Therefore, Jennie needs 40 cups of butter. However, since the options provided only go up to the nearest hundredth, we can round the answer to the nearest hundredth, which is 3.33 cups of butter.
