Input: To calculate the percentage change from 9000 to 15000, we need to follow the below steps:

Step 1: Find the difference between the new value (15000) and the old value (9000).

15000 - 9000 = 6000

Step 2: Divide the difference by the old value and multiply by 100 to get the percentage change.

(6000/9000) x 100 = 66.67%

Therefore, the percentage change from 9000 to 15000 is 66.67%. This means that the value has increased by 66.67% from its original value of 9000. Alternatively, we can say that the new value is 166.67% of the old value.
