Solving Percent Problems with Tape Diagrams

The video tutorial explains how to use tape diagrams to solve percent problems through three examples. The first example demonstrates calculating a 25% increase on $300. The second example shows how to find 19% of 120 by subtracting 1% from 20%. The final example illustrates calculating a 20% discount on a $60 pair of shoes. Each example uses a bar diagram to visually represent the problem and solution.
