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
If the recipe calls for 3 tablespoons of kernels and she uses 10 tablespoons of kernels, she uses 10/3 = <<10/3=3.33>>3.33 times the amount of kernels required.
Since she needs 1/2 cup of butter in the recipe and she uses 3.33 times the amount of kernels required, she needs 3.33*1/2 = <<1/2*3.33=1.665>>1.665 cups of butter. Answer: \boxed{1.67}.
To find out how much butter Jennie needs when using 10 tablespoons of kernels, we can set up a proportion using the given information:
1/2 cup of butter is needed for 3 tablespoons of kernels.
So, the proportion can be set up as:
(1/2) cup / 3 tablespoons = x cup / 10 tablespoons
To solve for x, we can cross multiply:
3 * x = (1/2) * 10
3x = 5
Divide both sides of the equation by 3:
x = 5/3
The rounded answer to the nearest hundredth is approximately 1.67.
Therefore, Jennie would need approximately 1.67 cups of butter when using 10 tablespoons of kernels.
To determine how much butter Jennie needs, we can use a proportion.
The given recipe calls for 3 tablespoons of kernels and 1/2 cup of butter. We can set up the proportion:
3 tablespoons of kernels / 1/2 cup of butter = 10 tablespoons of kernels / x cups of butter
To find x (the amount of butter needed when using 10 tablespoons of kernels), we can cross-multiply:
3 tablespoons of kernels * x cups of butter = 10 tablespoons of kernels * 1/2 cup of butter
Simplifying this equation, we get:
3x = 10 * 1/2
3x = 5
To solve for x (the amount of butter needed), we divide both sides by 3:
x = 5/3
Therefore, when Jennie uses 10 tablespoons of kernels, she needs approximately 1.67 cups of butter.
