Question

A colony of 50 bacteria double in size every 30 minutes. What will the population be 120 mintues from now?

Answer 1

800 bacteria

Explanation:

Over here, we have exponential growth.

So we have 50 bacteria

Every 30 minutes, it doubles in size

In 120 minutes, there are four 30 minutes.

So you do 50 * 2 * 2 * 2 * 2

Do that out and you get 800
