Challenge in the first week of July, a record 1,060 people went to the local swimming pool. In the
second week, 110 fewer people went to the pool than in the first week. In the third week, 140 more
people went to the pool than in the second week. In the fourth week, 295 fewer people went to the
pool than in the third week. What is the percent decrease in the number of people who went to the
pool over these four weeks?
