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. (1 point)
Since the recipe calls for 3 tablespoons of kernels, and Jennie is using 10 tablespoons, she is using 10/3 times the original amount of kernels.
Jennie needs 1/2 cup of butter, which is equal to 8 tablespoons.
Therefore, Jennie needs 8 * (10/3) = 80/3 = <<8*(10/3)=26.67>>26.67 tablespoons of butter. Answer: \boxed{26.67}.
To find out how much butter Jennie needs when using 10 tablespoons of kernels instead of 3, we can set up a proportion using the given information.
The original recipe calls for 3 tablespoons of kernels and 1/2 cup of butter. We know that there are 16 tablespoons in 1 cup, so 1/2 cup of butter is equal to 8 tablespoons.
Therefore, the proportion can be set up as:
3 tablespoons of kernels / 8 tablespoons of butter = 10 tablespoons of kernels / x tablespoons of butter
To solve for x, we can cross-multiply and divide:
3 * x = 10 * 8
3x = 80
x = 80 / 3 ≈ 26.67
So, when using 10 tablespoons of kernels, Jennie will need approximately 26.67 tablespoons of butter. Rounded to the nearest hundredth, she will need 26.67 tablespoons of butter.
To determine how much butter Jennie needs, we first need to find the ratio between the amount of kernels and the amount of butter in the original recipe.
The original recipe calls for 3 tablespoons of kernels and 1/2 cup of butter.
The ratio of kernels to butter is 3 tablespoons : 1/2 cup.
Now, we can use this ratio to find the amount of butter needed when using 10 tablespoons of kernels.
The new ratio becomes: 10 tablespoons : x cups.
To find x (the amount of butter in cups), we can set up a proportion:
3 tablespoons / 1/2 cup = 10 tablespoons / x cups.
To solve this proportion, we can use cross-multiplication:
(3 tablespoons) * (x cups) = (10 tablespoons) * (1/2 cup).
3x = 10 * 1/2.
3x = 10/2.
3x = 5.
Dividing both sides by 3:
x = 5/3.
Now we know that Jennie needs 5/3 cups of butter when using 10 tablespoons of kernels.
Rounding this answer to the nearest hundredth, Jennie needs approximately 1.67 cups of butter.
