How much Pizza do we order

Kim:

I am also wondering how much pizza we need to order? I am bad at guessing as I don't eat much these days, but Jon makes up for it. I am not sure how many a large pizza feeds. If I counted right there will be 14 adults and 10 kids. Thoughts on how many? Your grandma is wanting to send me money for them and I am not sure how much it will be. Thanks ladies! Count down is on!!

Heather:

Holly-how much pizza do we need. (Holly is good at this)

Kelly:

Hey, I heard Holly is good at this. Holly - how much pizza do you think we need?

Holly:

I want all you smarty pants to know that I emailed Kim right away and said  "How many pieces of pizza are in a Casey's pizza?" I mean, I need to know what I'm working with here, people.  I take size of pizza, thickness of crust, and how many Burleys are in attendance before I make an approximate guess.

Joe makes fun of me for my pizza-specific preferences. Tavern Pizza? Cheeseburger. End of story.  Happy Joes? BLT. Hands Down.  Caseys? Taco or Supreme.  Pizza Hut? Pan Crust, Extra Cheese, Vegetarian.  And, then if Joe doesn't remember what kind of pizza I get at which place, I get completely annoyed.

Since this event has a large amount of Burleys, I will guess high and will not disappoint.
