Mario Agnello is opening a new pizza shop in town. He plans to offer a 12 -inch diameter pizza and an 18 -inch diameter pizza. He has set the price of a 18 -inch cheese pizza at $ 8.00 , 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 18 -inch cheese pizza?
