ChatGPT (I gave no hints in my prompt):

To estimate how many people the *12 pizzas* were for, we can use a standard rule of thumb:

### General pizza math:

* A *large pizza* usually has *8 slices*. * Most people eat *2–3 slices*.

So:

* *12 pizzas × 8 slices = 96 slices total* * If people ate:

  * **2 slices each** → feeds **48 people**
  * **3 slices each** → feeds **32 people**

Since this was for a *team* within a 5,000-employee company — probably a local team (not the whole company) — the number of people was likely in the *25–40* range.

### Final Estimate:

*12 pizzas would reasonably feed about 30 to 40 people*, assuming average appetites.

Better than AI: ask someone who has ordered lots of piazza recently.

You need more than you think as not all pizzas will be the same flavour. The vegetarian ones will get eaten immediately by people who aren’t vegetarian. Then the complaints roll in.

Apply this to various other pizza type.

Order 1 pizza for every two people.
