A city's population grew from 10,000 people in 1990 to 40,000 people in 2010. If the population continues to grow exponentially at the same rate, what will it be in 2030?

Answer 1

Greetings! Lets solve this shall we ?

So, we must find the rate of change between the number of people growing between the years. Then, we notice that the population grows 30,000 people every 20 years! Therefore, in the year 2030, the population will be at 70,000 people!

I hope this helped!
