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.
o 1.50
o 1.67
o 3.33
o 1.66
To find out how much butter Jennie needs, 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:
3x = 12 * 10
3x = 120
Dividing both sides by 3, we get:
x = 40
Rounding to the nearest hundredth, Jennie needs approximately 40 cups of butter. Therefore, the correct answer is o 1.67.
