Answer 1

34175 people will live in Pattersonville 8 years from now

Explanation:

Initial population of Pattersonville =40,500

We are given that The census indicated that the population of the town has been decreasing by 2.1% per year .

Now we are supposed to find If this trend continues , approximately how many people will live in Pattersonville 8 years from now

Formula :
`N(t)=N_0(1-r)^t`

Where N(t)= Population after t years

`N_0`= Initial population

r = rate of decrease = 2.1 %=0.021

t = 8 years

Substitute the values in the formula :

So,
`N(8)=40500(1-0.021)^8`

N(8)=34175.63223

So, 34175 people will live in Pattersonville 8 years from now
