To find the percentage change from 500 to 8000, we need to first calculate the difference between the two numbers.

Step 1: Difference = Final Value - Initial Value

Difference = 8000 - 500

Difference = 7500

Step 2: Next, we need to find the absolute value of the difference. This is because percentage change is always calculated as a positive value.

Absolute Difference = |Difference|

Absolute Difference = |7500|

Absolute Difference = 7500

Step 3: Now, we can calculate the percentage change using the formula:

Percentage Change = (Absolute Difference / Initial Value) x 100

Percentage Change = (7500 / 500) x 100

Percentage Change = 1500%

Therefore, the percentage change from 500 to 8000 is 1500%. This means that there was an increase of 1500% from 500 to 8000.
