Solving Percent Problems with Tape Diagrams

This video tutorial demonstrates how to use bar diagrams, also known as tape diagrams, to solve percent problems. It provides two examples: one with a bar divided into four equal parts representing $16, and another with a bar divided into ten equal parts representing $50. The tutorial explains how to label dollar amounts and percentages on the bar, and how to use these labels to solve percent problems. The video concludes with a brief summary and a preview of more challenging percent problems in the next lesson.
