**Percentage change from A to B**

The formula for percentage change is (New value - Old value)/ Old value × 100.

- Example 1: Percentage change from 50000 to 55000
- (55000-50000)/50000 × 100
- 5000/50000 × 100 = 10%

Since the percentage is positive, there is a percentage increase of 10% from 50000 to 55000.

- Example 2: Percentage change from 1000 to 800
- (800-1000)/1000 × 100
- -200/1000 × 100 = -20%

Since the percentage is negative, there is a percentage decrease of 20% from 1000 to 800.
