Description

Percent increase is used to quantify the growth in value over time, expressed as a percentage of the original value. It is commonly used in finance, economics, and everyday scenarios such as salary increases and population growth.

For example, if the price of a stock rises from \$50 to \$75, the percent increase is calculated as 

(75 − 50)/50 × 100 = 50%

In math education, understanding percent increase helps students analyze changes in data, make informed decisions, and apply mathematical reasoning to real-world problems.

Teacher’s Script: "If a product's price goes up from \$40 to \$60, the percent increase is (60 − 40)/40 × 100 = 50%."
