Percent Change - Concept

Concept Concept (1)

In math, sometimes we want to calculate the percent that something changes. Percent changes are often seen in word problems and are useful in many real world situations, for example when shopping sales or when calculating a tip. A percent change is a way to describe how much a quantity increases or decreases. For example, when you buy an item with tax, the tax is the percent change from the original price to what you paid.
