The table shows population data year 2000 118,000 2006 138,000 a. what is the percent of change to 2006 b. Use this percent of change to predict the population in 2012

ANow look, in the year 2000, the population is 118,000
In the year 2006 is 138,000
To find the percent change |Original Amt - New Amt|                                            --------------------------------       x100
                                                 Original Amt

So for this question you would do 118,00 - 138,000 (ignore the negativesss)

     and you get -20,000 (ignore the negatives) and then you get 20,000

Now, you have to do 20,000 divided by 118,000 x 100

20,000 divided by 118,000 and you get 0.169491525

Now you have to multiply 0.169491525 by 100

0.169491525 x 100 = 16.9491525

Round this and you get a 16.9% change.

b) To predict the population in 2012 you will have to do 138,000 + 16.9%

To calculate this you have to do this:
                                                 138,000 x 0.169 = 23322

Now add 23,322, to 138,000 and you get 161,322.

A) 16.9%

B) 161,322

hope this helped :)
