The population of the small town of Parks in 2000 was estimated to be 3,901 people with an annual rate of decrease of about 1.8%
trasher [3.6K]

<u>Answer-</u>

<em>The estimated population in 2013 is </em><em>3081.</em>

<u>Solution-</u>

This can be represented as exponential decreasing function,

y=a(1 - r)^t

Where,

  • a = starting amount
  • r = rate
  • t = years

Putting the values,

y=3901(1 - 0.018)^{13}

=3901(0.982)^{13}

=3901\times 0.7897

=3080.62

As population can not be in fraction, so after rounding off the estimated population in 2013 is 3081.
