the percent change when a quantity changes from 66 to 54:
the difference is 66-54=12
here you need to find x% or x%2F100 of 66 equal to 12

%28x%2F100%2966=12....solve for x

%28x%2F50%2933=12

33x%2F50=12
33x=12%2A50
x=600%2F33
x=18.18181818
highlight%28x=18.18%29%=> your answer

check:
18.18% of 66 is:
%2818.18%2F100%2966
=%2818.18%2A66%29%2F100
=1199.88%2F100
=11.9988....round it to whole number
=12
66-12=54
