Quiznos on Craig Math Fail #fb
I was at the Quiznos near CMU on Craig St today and noticed their 2 for $5 deal. For $5, you get to choose two items from their list of 20 items, which includes 7 salads, 5 Bullets, 4 Sammies, and 4 soups. From this menu, Quiznos says you can make over 250 combinations. But they’re wrong!
The actual number of combinations is . is for the number of combinations of distinct items and the final is for the number of choices where you get two of the same item.
I think I know why they say 250 though. The official Quiznos menu has 23 items, for a total of 253 combinations. Quiznos franchises must source promotional material from Quiznos corporate, which prints everything up and assumes the 23 items.
This isn’t as satisfying as catching Quiznos in a fail-moment, but it serves to prove that math is useful!
Thanks to Alan and Kevin for some math help. (Alan uses pirates and gold, but I like my reasoning better.)
