Jennie is making popcorn. The recipe calls for 12 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? Round your answer to the nearest hundredth. (1 point)

Answer 1

We can set up a proportion to solve for how much butter Jennie needs. Let's call the amount of butter she needs x:

12 cups / 3 tablespoons = x / 10 tablespoons

Cross-multiplying, we get:

12 * 10 = 3x

120 = 3x

Dividing both sides by 3, we get:

40 = x

So, Jennie needs 40 cups of butter. Rounded to the nearest hundredth, this is 40.00 cups. Answer: \boxed{40.00}.
