Geeni is making popcorn. The recipe calls for 1/2 cup of butter, 3 tablespoons of kernels and 1 teaspoon of salt. If she uses 10 tablespoons of kernels how much butter does she need

To make the popcorn, Geeni needs 1/2 cup of butter, 3 tablespoons of kernels, and 1 teaspoon of salt.

If she uses 10 tablespoons of kernels, she needs to adjust the recipe accordingly.

The original recipe asks for 3 tablespoons of kernels, so for 10 tablespoons, Geeni needs to multiply the butter by 10/3.

Therefore, Geeni needs:
1/2 cup of butter * (10/3) = 5/6 cup of butter.

So, Geeni needs 5/6 cup of butter.
