A town's population is currently 100,000 people. The mayor discovered that the population is declining at a rate of 4% annually. If this rate continues, what will the
population of the town be in 5 years? Round your answer to the nearest whole number.
O 96,000 people
O 81.537 people
O 121,665 people
O 85,873 people

Answer 1

Based on the current population and the rate of decrease, the population in five years will be 81,537 people.

What is the population in five years?

This can be found by the formula:

= Current population x ( 1 - rate) ^ number of years

Solving gives:

= 100,000 x ( 1 - 4%)⁵

= 100,000 x 0.8153726976

= 81,537 people

In conclusion, option B is correct.
