Question

In the first week of July, a record 1,060 people went to the local swimming pool. In the second week, 105 fewer people went to the pool. In the third week, 135 more people went to the pool than in the second week. In the fourth week, 136 fewer people went to the pool than in the third week.

What is the percent change in the number of people who went to the pool between the first and last weeks?

Answer 1

To find the percent change in the number of people who went to the pool between the first and last weeks, we can use the formula:

percent change = (new value - old value) / old value x 100

First we need to find the number of people who went to the pool in the last week, which is the number of people who went in the first week minus 105, plus 135, minus 136.

So:

Last week = 1060 - 105 + 135 - 136 = 954

Then we can calculate the percent change:

percent change = (954 - 1060) / 1060 x 100 = -10%

So the percent change in the number of people who went to the pool between the first and last weeks is -10%. This means that the number of people who went to the pool in the last week is 10% less than the number of people who went in the first week.

Answer 2

The percent change in the number of people who went to the pool

between the first and last week is 10% less

Explanation:

The given is:

. In the first week of July, a record 1,060 people went to the local swimming

pool

In the second week, 105 fewer people went to the pool

⚫ In the third week, 135 more people went to the pool than in the second week

. In the fourth week, 136 fewer people

went to the pool than in the third week

We need to find the percent change in the number of people who

went to the pool between the first and last weeks

::There were 1060 people in the 1st week

There were 105 fewer people in the 2nd week .. The number of people in the 2nd week =

1060 - 105 = 955

.. There were 955 people in the 2nd week

:: There were 135 more people in the 3rd

week than the 2nd week

There were 955 people in the 2nd week

.. The number of people in the 3rd week = 955 + 135 = 1090

There were 1090 people in the 3rd week

:: There were 136 fewer people in the 4th week than in the 3rd week

There were 1090 people in the 3rd week

.. The number of people in the 4th week =

1090-136 = 954 .. There were 954 people in the 4th week

Let us find the change from 1st week to last week

: There were 1060 people in the 1 st week

There were 954 people in the last week

.. The change = 1060-954 = 106

:: Percent change =

Change

Original * 100%

.. Percent change = * 100%

106

1060 Percent change = 10%

The percent change in the number of people who went to the pool
