>Two 12 Inch Pizzas have less Pizza than one 18 inch pizza

Love this one. Always go for the biggest pizza you can

No. While two 12" pizzas have more pizza than one 18" pizza, it's possible for the two 12" pizzas to be a better value.

If the total price of the two 12" pizzas is $7.20, for example, they are a better value than the 18" pizza once the price of the 18" pizza is greater than $8.10. More generally, the two 12" pizzas are a better value if the 18" pizza's price is higher than 112.5% of the two 12" pizzas' total price.

But that's almost never the case.

How do you know, unless you do the calculation?

Don't know about you, but I have never seen any place that charges more for one large pizza than for two medium pizzas.

For example the place by me charges 11 for a 12 inch pizza and 25 for a 24 inch. That's 4x the pizza for a little over twice the price!
