It’s the third day of school and you’re lost in your new school… again. You take a right turn into what you thought was your algebra classroom and find yourself in an abandoned classroom. You turn to exit, but realize the door has locked behind you.
Great, just great. Mr. Lazenby has already told you that if you’re late again, you won’t get to go to the big dance! (You’ve already paid the deposit on a limo, so that would be so unfair!)
Luckily, you see the custodian’s box labeled “Spare Master Keys.” You examine it to see that there are six locks on it. If you can unlock this box, you’ll find a key and get to algebra class on time!
