Question

A town has a population of 18000 and grows at 2% every year. To the nearest tenth of a year, how long will it be until the population will reach 26700?

^^

Answer 1

19.9

Explanation:

we can write the following equation

18000(1.02)^n

where n is the number of years

so we have

26700=18000(1.02)^n

solve for n

1.483=1.02^n

use logs to solve for n

n=19.9
