In July:

First week:

Number of people went to the local swimming pool =1040

Second week:

110 fewer people went to the pool than in the first week

so,

Number of people went to the local swimming pool =1040-110

=930

Third week:

130 more people went to the pool than in the second week

so,

Number of people went to the local swimming pool =930+130

=1060

Fourth week:

228 fewer people went to the pool than in the third week

so,

Number of people went to the local swimming pool =1060-228

=832

Decrease in number of people over four week= number of people in first week - number of people in fourth week

Decrease in number of people over four week=1040-832

=208

now, we can find percentage
