In this video from *Cyberchase*, Bianca is lured into a store when she sees a 50% off sale sign in the window. She soon realizes that even when items are 50% off, the final bill can still be a lot of money. In the accompanying classroom activity, students create sales of their own by selecting an item from an advertisement and calculating the savings for 10%, 25%, 50%, and 75% off. This resource is part of the Math at the Core: Middle School Collection.
