Percentage Change Word Problems
Learn how to apply percentage change in real-life situations with step-by-step examples.
Example 1:
Income was $59,546 in 2023 and $65,362 in 2024.
Find the percentage change:

Find the percentage decrease:
= (250 − 200) ÷ 250 × 100
= 50 ÷ 250 × 100
= 20% decrease in price
Example 3:
Your website traffic grew from 1,200 visits to 1,500 visits.
= (1,500 − 1,200) ÷ 1,200 × 100
