Understanding Percent Increases

The video tutorial from MooMooMath explains how to calculate percent increases, a common question in word problems. It provides two examples: calculating the percent increase in student population from 2010 to 2011 and from 2010 to 2012. The tutorial outlines the rule for finding percent increases by taking the difference between two values, dividing by the original amount, and converting the result to a percentage. The video concludes with a summary of the method and encourages viewers to apply the learned concepts.
