To determine how much butter Jennie needs, we can use a proportion:
12 cups of butter is to 3 tablespoons of kernels as X cups of butter is to 10 tablespoons of kernels.
Upon solving this proportion, we can find the value of X, which represents the amount of butter Jennie needs.
12/3 = X/10
Cross multiplying, we get:
3X = 120
Dividing both sides by 3, we find:
X = 40
Therefore, Jennie needs 40 cups of butter. However, since the answer choices are rounded to the nearest hundredth, the closest option is 1.66.

Jennie 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? Round your answer to the nearest hundredth
To find out how much butter Jennie needs, we need to use a proportion.
The ratio of kernels to butter in the original recipe is 3 tablespoons of kernels to 12 cups of butter.
We can set up the proportion as follows:
3 tablespoons / 12 cups = 10 tablespoons / x cups
To find x (the amount of butter Jennie needs), we can cross-multiply and solve for it:
3x = 10 * 12
3x = 120
Dividing both sides by 3:
x = 120 / 3
x = 40
Therefore, Jennie needs 40 cups of butter.
However, the question asks for the answer rounded to the nearest hundredth, so the answer is 40.00.
To find out how much butter Jennie needs if she uses 10 tablespoons of kernels, we need to use a proportion based on the ratio of kernels to butter in the original recipe.
The original recipe states that for 3 tablespoons of kernels, Jennie needs 12 cups of butter. Therefore, the ratio is 3 tablespoons of kernels to 12 cups of butter.
To find out how much butter Jennie needs if she uses 10 tablespoons of kernels, we can set up a proportion:
3 tablespoons of kernels / 12 cups of butter = 10 tablespoons of kernels / x cups of butter
Cross-multiplying, we get:
3 tablespoons of kernels * x cups of butter = 12 cups of butter * 10 tablespoons of kernels
Simplifying, we have:
3x = 120
Dividing both sides by 3, we get:
x = 40
Therefore, if Jennie uses 10 tablespoons of kernels, she would need 40 cups of butter. However, since we are asked to round the answer to the nearest hundredth, the final answer would be 40.00 cups of butter.
