Question

Suppose a city with population 800,000 has been growing at a rate of 7% per year. If this rate continues, find the population of this city in 17 years.

Answer 1

1,752,000

Explanation:

1. First you have to take the 7% and multiply that by the years whish is 17 so that way you know your total percentage of growth which is 119%

2. Second you then need to find how much 1% is to find out our total growth in population so you take 800,000 and divide that by 100 since there's only 100% and you get 8,000.

3. Now you take the 8,000 and multiply that by the percentage of the growth that you have which is 8,000*119 and you get 952,000

4. Lastly all you have to do is add the growth of the population to the population you already have so 800,000+952,000=1,752,000
