Question

A city doubles its size every 99 years. If the population is currently 600,000, what will the population be in 198 years?

Answer 1

Divide 198 by 99 to get 2. The current population is 600000 so multiply that by itself to get 360000000000, multiply that number by itself to get 1.296E23

Answer 2

The answer is 1,200,000. Divide 198 by 99 to get 2. Multiply 600,000 by two.
