If the recipe calls for 3 tbsp of kernels and 1/2 cup of butter, the ratio of kernels to butter is 3 tbsp : 1/2 cup.
To find how much butter Jenny needs when using 10 tbsp of kernels, we can set up a proportion using the given ratio:
3 tbsp / (1/2 cup) = 10 tbsp / x
Cross-multiplying gives us:
3 tbsp * x = (1/2 cup) * 10 tbsp
3x = 5 tbsp
x = 5 tbsp / 3
x ≈ 1.67 tbsp
Therefore, Jenny needs approximately 1.67 tbsp of butter when using 10 tbsp of kernels.
