Mario Agnello is opening a new pizza shop in town. He plans to offer a twelve-inch diameter pizza and an eighteen-inch diameter pizza. He has set the price of a twelve-inch cheese pizza at eight dollars, based on the amount of ingredients needed to cover that size crust. If Mario would like to keep the pricing proportional, what should he charge for an eighteen-inch cheese pizza?
