Input: To calculate the percentage change from 1500 to 2000, we need to follow the below steps:

Step 1: Find the difference between the new value (2000) and the old value (1500).

2000 - 1500 = 500

Step 2: Divide the difference by the old value (1500) and multiply by 100 to get the percentage change.

(500/1500) x 100 = 33.33%

Therefore, the percentage change from 1500 to 2000 is 33.33%. This means that the value has increased by 33.33% from its original value of 1500. Alternatively, we can say that the new value (2000) is 133.33% of the old value (1500).
