**Let's get a little
trickier...**

**If we start with
200
alien amoebas and each amoeba splits into
1.7
amoebas every 12
hours, how many amoebas will there be in a week?**

**
Set it up and think!**

**
split factor
=
1.7**

**
initial population
=
200**

**
number of splits
=
?**

**
Our split factor is for 12
hours...**

**
There are 14
chunks of these in 7
days...**

**
number of splits
=
14**

**
**

**YOUR TURN:**

**If we start with
30
alien amoebas and each amoeba splits into
1.15
amoebas every minute, how many amoebas will there be in
an hour and a half?**

**Here's
how I'd like for you to remember this formula:**

* I don't want you to memorize this thing with a
t
up
there.

**t
usually stands for "time." In the next sections, we'll have
years, days and hours -- and these will NOT always represent the
number of splits! You'll see.**
