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

y number of pizzas will be ordered, each with 8 slices.

00:23

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.”
