Tuesday's (Belated) Teaser

Of course you can do it. One step at a time, there's nothing needed to solve this that we have not done.

Each correct teaser is worth 5 additional points (two correct = a 70% instead of a 60% on a test, for example).

Since this teaser was given late, answers, with work showing, can be submitted or emailed before the end of school on Monday, November 2.
