To find out how much butter Jennie needs if she uses 10 tablespoons of kernels, we need to find a ratio between the amount of kernels and the amount of butter in the original recipe.
Original recipe:
- 3 tablespoons of kernels requires 1/2 cup of butter
Ratio:
- 3 tablespoons of kernels requires 1/2 cup of butter
- 1 tablespoon of kernel requires 1/2 cup of butter divided by 3, which is 1/6 cup of butter
Now, we can calculate how much butter Jennie needs if she uses 10 tablespoons of kernels:
- 10 tablespoons of kernels require 10 * (1/6) cup of butter
- 10 * (1/6) = 10/6 = 1.67
Therefore, Jennie needs approximately 1.67 cups of butter. Rounding to the nearest hundredth, the answer is 1.67. So the correct answer is 1.67.
