Exploring Percentage Multipliers and Their Effects

This video tutorial explains how to use percentage multipliers to calculate percentage changes, both increases and decreases. It covers the conversion of percentages to multipliers and provides examples to illustrate the process. The tutorial also includes a contextual example of calculating the final price of a TV after multiple discounts, demonstrating the efficiency of using multipliers for such calculations.
