The answers given are correct. But, just look at the logic:
First: Since the number got larger in going from 125 to 130
we can immediately state the difference will be an INCREASE
As to the percentate change:
We need to know "What percent of 125 is 130?"
130 = (x/100)(125)
x = 130(100)/125 = 104%
Thus, 130 is 104% of 125, giving an increase of 4%
