How to approach percent increase & decrease
Percent change compares the amount of change with the original value: percent change = change ÷ original. The sign of the change determines whether it is an increase or decrease.
Always divide by the starting value, not the ending value. Convert the decimal quotient to a percent and state the direction in the final answer.
Learning objectives
- Calculate absolute and percent change
- Distinguish increase from decrease
- Apply discounts and markups
Skills to review first
- Percent calculations
- Decimal division
- Identifying original and new values
Worked example
Follow the reasoning step by step
A price rises from $50 to $62. Find the percent increase.
- Find the change: 62 − 50 = 12.
- Divide by the original value: 12 ÷ 50 = 0.24.
- Convert 0.24 to 24%.
- State that the change is an increase.
Solution: 24% increase.
