Question

the population of a city grows 7% each year. if it’s current population is 450,000, in how many years will the city’s popular get to 1,000,000?

Answer 1

It will take approximately 17 1/2 years for the city to reach a population of 1,000,000.

Step by Step Explanation:

7% of 450,000 is 31,500

450,000 to 1,000,000 means you need another 550,000 people in your population.

So take 550,000 divided by 31,500, which equals 17.46, which then rounds up to 17.5 years.

17.5 x 31,500= 551,250

That is how long it will take to reach 1,000,000 population count when the population only increases 7% each year.
