Shmoopy question coming your way in three… two… one…
- 00:08
Papa John is hosting Thanksgiving dinner. Unfortunately, his family always pressures
- 00:12
him into serving pizza, so the turkey has ended up in the garbage. Again.
- 00:17
Papa John expects to have x number of guests,
- 00:19

The number of pizza slices for every person would be 8y over x.
- 00:29
If it turns out later that two more guests come by for dinner,
- 00:32
but the number of pizzas remains the same…
- 00:34
…which of the following would be the new expression that gives the number of pizza
- 00:38
slices available to each person?
- 00:40
And here are the potential answers...
- 00:46
So… what is this question asking?
- 00:48
Well, it’s just about the carbs, really.
- 00:50
We’re getting less pizza when these interlopers – uninvited Turkey-day crashers – show up.
- 00:57
The ratio is just pizzas to people and we’ve added 2 people…
- 01:01
…so we can add a 2 to the x part below and get the right equation – answer is C.
- 01:06
As in… “Carbo-loading.”
