Answer:
<u>Part A:</u> The percent of change is about a <u>16.95%</u> increase.
<u>Part B:</u> The predicted population in 2019 is <u>158,000</u> people.
Step-by-step explanation:
Part A: Find the percent of change.
The percent of change =
At 2007 ⇒ 118,000
At 2013 ⇒ 138,000
So, during 6 years, the change = 138,000 - 118,000 = 20,000
The percent of change =
∴The percent of change is about a <u>16.95%</u> increase.
<u>Part B: Find the predicted population.</u>
The percent of change from 2007 to 2013 is a <u>16.95%</u> increase.
So, the percentage increase during 6 years is 16.95.
So, from 2013 to 2019 is another 6 years.
So, the percentage is predicted = 16.95%
∴ the same change of increasing is expected = 20,000
∴The predicted population in 2019 is = 138,000 + 20,000 = 158,000
The predicted population in 2019 is <u>158,000</u> people.
