Algebra 2 cell division word problem

[jenniferlove]

Here is the problem...

A single cell divides every 5 minutes. How long will it take for one cell to become more than 10,000 cells?

...I don't know where to start. Do I use the formula A(t)= ar^t ?

Help!!!!!

Answer these questions:

In 5 minutes, how many cells do you have?

In 10 minutes how many cells do you have? (remember there are new cells now which also divide)

In 15 minutes? 20? 25?

See a pattern?
