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
To calculate the amount of butter Jennie needs, we can set up a proportion.
We know that 3 tablespoons of kernels require 12 cups of butter.
Let's represent the unknown amount of butter Jennie needs as x cups:
3 tablespoons / 12 cups = 10 tablespoons / x cups
To find x, we can cross-multiply and solve for x:
3x = 10 * 12
3x = 120
x = 120 / 3
x = 40
Therefore, Jennie needs 40 cups of butter. Rounding to the nearest hundredth, the answer is 40.00 cups.
Given that the recipe calls for 3 tablespoons of kernels and she uses 10 tablespoons, we can find the ratio of kernels used to the amount of butter needed.
Ratio of kernels used to butter needed = 10 tablespoons / 3 tablespoons
To find the amount of butter needed, we can set up a proportion:
10 tablespoons / 3 tablespoons = x cups / 12 cups
Cross-multiplying, we have:
10 tablespoons * 12 cups = 3 tablespoons * x cups
120 tablespoons = 3 tablespoons * x cups
Dividing both sides by 3 tablespoons, we get:
40 cups = x cups
Therefore, Jennie would need 40 cups of butter when she uses 10 tablespoons of kernels.
To find out how much butter Jennie needs if she uses 10 tablespoons of kernels, we need to use proportions.
First, let's determine the ratio between the original amount of kernels and the amount of butter.
The original recipe calls for 3 tablespoons of kernels and 12 cups of butter.
So the ratio of kernels to butter is 3 tablespoons : 12 cups.
Now, we can set up a proportion using this ratio:
3 tablespoons / 12 cups = 10 tablespoons / x cups (where x represents the unknown amount of butter).
To solve for x, we can cross-multiply and then isolate the variable:
3 tablespoons * x cups = 12 cups * 10 tablespoons
Now, we can simplify the equation:
3x = 120
Finally, divide both sides of the equation by 3 to solve for x:
x = 120 / 3
x = 40
Therefore, Jennie would need 40 cups of butter if she uses 10 tablespoons of kernels. However, since we need to round our answer to the nearest hundredth, the answer would be 40.00 cups of butter.
