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

You could answer this by multiplying the current population of 800,000 by 1.07 (1.07 represents the annual growth rate of population) and do that 17 times. But that would take a while.

To do this faster, you would first calculate (1.07)¹⁷ and then multiply this by 800,000.

So, 800,000 x (1.07)¹⁷ = 2,527,052
