25% change

Explanation:

You take how much was added and divide that by how much you originally had. So in this question, from 80 to 100 was a change of 20, so we use the equation of (change of value) / (original value).

Change of value: 100-80 = 20
Original value: 80
Final value: 100

Using the equation, 20/80 we get 0.25 and multiply that by 100 to get 25%.
