Question

The population of a town decreases exponentially at a rate of 1.7% per year.

The population now is 250 000. Calculate the population at the end of 5 years
Give your answer correct to the nearest hundred.

Answer 1

Answer: 229,500 people to the nearest hundred

Explanation:

Population decreases exponentially at 1.7% per year in a town that is currently 250,000 in number.

Population in 5 years = 250,000 * ( 1 - 1.7%) ⁵

= 250,000 * 0.917841286185143‬

= 229,460

= 229,500 people to the nearest hundred
