If Jenny 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 around the answer to the nearest hundredth
1.66
1.67
1.50
3.33
If the original recipe calls for 3 tablespoons of kernels, and she uses 10 tablespoons instead, she increases the amount of kernels by a factor of 10/3. Since the recipe calls for 1/2 cup of butter, the amount of butter needed will also be increased by a factor of 10/3.
Therefore, she needs approximately 1/2 * (10/3) = 5/3 = 1.67 cups of butter.
Therefore, the answer is 1.67.
