Types of Percent Change
- Percent Increase: When the new value is higher than the old value. For example, if a stock’s price rises from $50 to $60, there is a 20% increase.
- Percent Decrease: This happens when the new value is smaller than the old value. For example, if an item’s price drops from $80 to $60, there is a 25% decrease.
