This document provides examples for writing and solving percent equations. It begins with an anticipatory set asking students to write and solve an equation to find the gratuity on a $72 bill if an 18% gratuity is left. The document then provides 8 examples for students to write and solve percent equations. It concludes by asking students to find 214% of 700 and describe how this final example differs from the previous examples solved in class.
