To find out how much butter Jennie needs, we can set up a proportion:
3 tablespoons of kernels = 1/2 cup of butter
10 tablespoons of kernels = x (unknown amount of butter)
Using cross-multiplication, we can solve for x:
3 * x = 10 * 1/2
3x = 5
x = 5/3
x ≈ 1.67
So, Jennie needs approximately 1.67 cups of butter. Rounded to the nearest hundredth, this is 1.67
