<PRE><B>Question 181705</B>
A cell divides into two identical copies every 4 minutes. How many cells will exist after 5 hours? 
This is where I am at so far: 
60 minutes = 1 hour
300 minutes = 5 hours
a cell divides into 2 every 4 minutes
-------------
Growth formula:
A(t) = A(o)(2)^(t/4) where t is number of minutes after t = 0
------------------------------------------------------------------
A(300) = 1*2^(300/4)

A(300) = 2^(75)

A(300) = 3.77x10^22 cells
