How many pizzas are ordered in the US on Super Bowl Sunday?
How to approach it
Start with households watching the game and the share that hosts or joins a gathering, then estimate pizzas per gathering.
How a strong answer opens
“I'll start with households watching the game, then the share that orders pizza or goes to a party where pizza is ordered, then pizzas per order.”
Outline of a strong answer
Try answering out loud for a few minutes before you open this.
- State households, about 130 million
- Share watching the game
- Share ordering pizza
- Pizzas per ordering household or party
- Multiply households by pizzas per household
- Sanity-check: compare with a normal Sunday and with pizza shop capacity
Where this question usually goes wrong
Assuming every viewer orders their own pizza instead of counting by household or party.
