This was a -20% change.

The formula for calculating the percent change is:

#p = (N - O)/O*100# where #p# is the percent change, #N# is the New Value and #O# is the Old Value.

We can substitute the values provided in the problem and solve for #p#:

#p = (60 - 75)/ 75*100#

#p = -15/75*100#

#p = -1500/75#

#p = -20#
