A change from 60 to 75 represents a positive change (increase) of 25%

it is increased by 15 so we need to figure out what percent 15 is of 60 and the best way to do that is to set up a proportion

15       x
----- = ----
60      100

then cross multiply and divide

15 times 100=1500/60=25

the percent of increase is 25%

I hope I've helped!
