Percent Increase | MathHelp.com

This lesson covers percent increase. Students learn to find the percent increase or percent decrease between two numbers, using the following formula: amount of change/ original number. For example, to find the percent decrease if the price changes from $60 to $39, since the amount of change is $21, and the original number is $60, the percent decrease is $21/$60, which simplifies to 0.35. And remember that the answer is a percent, so move the decimal point two places to the right, to get 35%. So if the price changes from $60 to $39, the percent decrease is 35%.
