How many days would it take for the whole world to become zombies?
- On day 1, there is just one zombie (patient zero)
- Each day, every zombie infects one person (so the number of zombies doubles)
- The current world population is 7.9 billion people

Realistically, each zombie is probably going to infect more than one person per day. Choose a better estimate of how many people each zombie will infect, and model how many days it will take with that new estimate. (Hint: if you think each zombie will infect 3 people per day, the number of zombies will quadruple (x4) each day).
