To find the percentage change from 35 to 30, we need to first calculate the difference between the two numbers.

Step 1: Difference = Final Value - Initial Value

Difference = 30 - 35

Difference = -5

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 = |-5|

Absolute Difference = 5

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

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

Percentage Change = (5 / 35) x 100

Percentage Change = 14.29%

Therefore, the percentage change from 35 to 30 is -14.29%. This means that there was a decrease of 14.29% from 35 to 30.
