The Pizza Problem
A group of friends decide to meet for pizza, and one friend calls ahead to order the pies. However, three people in the group do not show up at the pizza parlor. The friends who do show up figure that they each add $3 to their original share, to cover the bill, which totals $70. How many friends eat pizza?
Hint #1 - Think About It
- We know the total they paid for the pizza is $70.
- How would you decide with your friends how much you should pay for pizza if this was you?!
- What would you do if one of them didn't show up? Two of them? Three of them
If you went out with 2 other friends of yours, and you all decided to split a large pie that was $15, how much would each friend have to pay?
Think about this question just like that!
Hint #2 - The Formula
(# of people expected) x ($ per person) = $70 ?
We can use this formula seen above to help us plug-in & solve.. Now we have TWO HINTS!

Hint #3 - Pieces of the Formula!
(# of people expected)
Think about who actually shows up? |
($ per person)
How would you figure out how much per person if no one left? |
Think about the pieces of the formula you saw in HINT #2.. Use this HINT #3 to help you build upon it and solve!
