Final answer:
Without a specific cookie recipe, we use the classic pound cake proportions to determine that you can use all 5 cups of butter, 5 cups of flour, 5 cups of sugar, and 5 eggs to make an unspecified number of cookies. This leaves you with 4 cups of flour, 0 cups of butter, 0.5 cups of sugar, and 3 eggs remaining.
Step-by-step explanation:
The number of cookies you can make depends on the specific recipe you're using, which isn't provided in the question. However, we can use the classic pound cake recipe as a reference to determine the proportions needed. One pound of each ingredient (eggs, butter, flour, and sugar) is required to bake a pound cake.
If you started with 9 cups of flour, 5 cups of butter, and 4.5 cups of sugar, and the recipe calls for equal amounts of these ingredients, then butter would be the limiting reactant since you have the least amount of it at 5 cups. Assuming you have a conversion of 1 cup to 1 pound (which isn't precise in reality but for the sake of this problem, let's assume it to be true), you would use 5 cups of each ingredient to make the cookies. Therefore, you are left with 4 cups of flour, no butter, and a half cup of sugar.
The number of eggs needed depends on the specific cookie recipe. Since the pound cake example uses a 1:1:1:1 ratio of flour, butter, sugar, and eggs, you would use 5 eggs. As such, you would have 3 eggs remaining.
