Final answer:

The percent decrease in the number of people who went to the pool over the four weeks is 10%.

Step-by-step explanation:

To find the percent decrease in the number of people who went to the pool over the four weeks, we need to calculate the difference between the number of people in the first week and the fourth week, and then find the percentage decrease.

First, let's find the number of people in each week:

  • Week 1: 1060 people
  • Week 2: 1060 - 110 = 950 people
  • Week 3: 950 + 140 = 1090 people
  • Week 4: 1090 - 136 = 954 people

Now, let's find the difference in the number of people between the first and fourth week:

1060 - 954 = 106 people

Finally, let's find the percentage decrease:

(106 / 1060) * 100

= 10%

The percent decrease in the number of people who went to the pool over the four weeks is 10%.
