Question

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 -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?

Show and explain your solution.

Answer 1

ratio of the area goes with the square of the ratio of the diameter, because the area is a square

Answer 2

thank you

Answer 3

so you start with \(\frac{12}{8}=\frac{3}{2}\) square to get
\[(\frac{3}{2})^2=\frac{9}{4}\] and then solve
\[\frac{9}{4}=\frac{x}{8}\] to find the price \(x\)
