Mathematically Turning The Page

Found a handy little tool for any of you looking to figure out how big of a cake to buy for your event! Bakers, please feel free to disagree with any of the information as this is your specialty ... this seems like a pretty good guide to me though. Deciphering it can be a bit of a challenge so I've made it as reader-friendly as possible for you.
