Suppose a city with population 400,000 has been growing at a rate of 2% per year. If this rate continues, find the population of this city in 22 years.

Sagot :

1. 400,000(1 + 0.02)^22, this is exponential growth

2. 400,000(1.02)^22

3. Because this is population, always round to the nearest whole number. The answer you get is 618391.86831, but the exact answer is 618,332

Hope this helps :)
