The following table provides the list of ingredients used, the cost to purchase the ingredients, and the amount of each ingredient required for a batch of \(12\) cookies.

Ingredient Cost of Ingredient Amount per Batch Cost per Batch
Brown Sugar \(\$2.90\) for \(5\) cups \(1\) cup
Eggs \(\$3.00\) for \(12\) \(1\)
Chocolate Chips \(\$9.48\) for \(3\) cups \(\frac{1}{2}\) cup
White Sugar \(\$2.48\) for \(10\) cups \(\frac{1}{4}\) cup
Butter \(\$4.98\) for \(2\) cups \(\frac{3}{4}\) cup
Flour \(\$9.00\) for \(40\) cups \(2\frac{1}{4}\) cup
