Question

The 2000 population of a city was 710​,000 and was increasing at the rate of 1.49 % each year. At that​ rate, when will the population be 1​ million?

Answer 1

23.1567

Explanation:

710000(1+1.49/100)ⁿ=1000000

710000×1.0149ⁿ=1000000

1000000÷710000=1.0149ⁿ

1.4084507=1.049ⁿ

log1.4084507=ⁿlog1.0149

log1.4084507/log1.0149=ⁿ
