Question

1.67
1.66
3.33
1.50

Answer 1

To find out how much butter Jennie needs, we can set up a ratio using the given information.

Given:
3 tablespoons of kernels = 12 cups of butter

10 tablespoons of kernels = x cups of butter

Using a proportion, we can set up the equation:

3/12 = 10/x

Cross-multiplying, we get:

3x = 12 * 10

3x = 120

x = 120/3

x = 40

Therefore, Jennie needs 40 cups of butter.

Rounding to the nearest hundredth, the answer is 1.67.

So the correct answer is 1.67.
