#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%#.
