Calculating Tips and Percentages

In this video, Sean Ian provides practical advice on calculating a 15% tip. The method involves moving the decimal point of the total bill to find 10%, then halving that amount to get 5%, and adding the two to get 15%. Examples with $20 and $23.41 bills are given, including rounding tips. The video concludes with a summary of the method and encourages viewers to practice.
