To find out how much butter Jennie needs, we can set up a ratio using the given information.
Given:
3 tablespoons of kernels = 12 cups of butter
10 tablespoons of kernels = x cups of butter
Using a proportion, we can set up the equation:
3/12 = 10/x
Cross-multiplying, we get:
3x = 12 * 10
3x = 120
x = 120/3
x = 40
Therefore, Jennie needs 40 cups of butter.
Rounding to the nearest hundredth, the answer is 1.67.
So the correct answer is 1.67.
