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?

@JA1 HELP?

anonymous · Answer

($8)/(12 inches)    =    ($x)/(18 inches)

You can (should) eliminate the $ and "inches":

8/12    =    x/18

So, just cross-multiply and solve for "x".  Can you do that or do you need help with that?

anonymous · Answer

This format might make it easier to see:$$\frac{ 8 }{ 12 } = \frac{ x }{ 18 }$$

anonymous · Answer

(12)(x) = (8)(18)

12x = 144     ->     x = 12 (dollars)

That's because :

8/12   =   12/18

They both equal 2/3
