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) Responses
To find the amount of butter needed, we can set up a proportion. Let x be the amount of butter needed:
3 tablespoons of kernels / 12 cups of butter = 10 tablespoons of kernels / x cups of butter
Cross multiplying, we get:
3x = 120
x = 120 / 3 = 40
Therefore, she needs 40 cups of butter.
what is 40 as a decimal
40 as a decimal is simply 40.00.
To find out how much butter Jennie needs, we need to calculate the ratio of the amount of kernels to the amount of butter in the recipe.
The recipe states that for 3 tablespoons of kernels, Jennie needs 12 cups of butter. We can set up a proportion to find out how much butter is needed for 10 tablespoons of kernels.
Let's set up the proportion:
(3 tablespoons of kernels) / (12 cups of butter) = (10 tablespoons of kernels) / (x cups of butter)
Now, let's solve for x:
(3/12) = (10/x)
To solve for x, cross-multiply:
3x = 120
Divide both sides of the equation by 3:
x = 40
Therefore, Jennie needs 40 cups of butter when she uses 10 tablespoons of kernels.
