You are at Safeway to buy ingredients for a cake to make for your best friend’s birthday. Your mom already bought the butter, sugar, and icing for your cake, and all you need to buy is the flour, two dozen eggs, and three quartz of milk. Let “f” denote the price of flour, “e” denote the price of a dozen eggs, and “m” denote the price of milk. Construct a polynomial expression, "C", that represents the total cost of your ingredients.
