Question

Suppose a city with population 400,000 has been growing at a rate of 7% per year. if this rate continues, find the population of this city in 19 years. The population in 19 year will be approximately...? ​

Answer 1

932,000

Explanation:

Put in fraction 400,000 over 1 multiplied by 7% over 100 because to find the percentage of something we always divide or multiply by 100, then cross cancell the two zeros of the 100 and two zeros of the 400,000

You are now left with 4,000 over 1 multiplied by 7 over 1

Do the rest and you will end up with 28,00 per year

Multiply that by 19 and add that amount with the first 400,000 and you will get 932,000 easy..

Hope this helps
