Answer 1

To determine how much butter Jennie needs when she uses 10 tablespoons of kernels, we can set up a proportion based on the original recipe.

Original Recipe Ratio:

• Butter: \( \frac{12 \text{ cups}}{3 \text{ tablespoons}} \)
• This simplifies to \( 4 \text{ cups of butter per tablespoon of kernels} \).

Ratios:

• 3 tablespoons of kernels require 12 cups of butter.
• To find out how much butter is needed for 10 tablespoons, we can set up the following proportion based on the previous ratio:

\[ \text{Butter needed} = \left( \frac{12 \text{ cups}}{3 \text{ tablespoons}} \right) \times 10 \text{ tablespoons} \]

Calculating:

1. Calculate the butter per tablespoon: \[ \frac{12 \text{ cups}}{3 \text{ tablespoons}} = 4 \text{ cups per tablespoon} \]

2. Multiply the amount of butter per tablespoon by the number of tablespoons (10): \[ 4 \text{ cups} \times 10 = 40 \text{ cups} \]

Thus, if Jennie uses 10 tablespoons of kernels, she will need 40 cups of butter.

This value does not require rounding as it's a whole number.
