Maths Mystery! (Code Breaking)

Every Week the Whetu Team does a Math Challenge. It is a Mystery about The Mystery of the Murder at the Movies! I worked by myself because I haven't work by myself in ages!  This Week's Maths Mystery was different than normal Maths Mystery because It was just code-breaking no culprits no nothing! Well, it was really fun though. It was pretty easy so there was nothing challenging about this week's Maths Mystery. But the easiest part was the first slide because their were lest codes to break!
