Homework Help: Pre-Calc (exponential growth)

Posted by Phillip on Sunday, March 28, 2010 at 6:55pm.

A COLONY OF BACTERIA IS GROWN UNDER IDEAL CONDITIONS IN A LAB SO THAT THE POPULATION INCREASES EXPONENTIALLY WITH TIME. At the end of the three hours, there are 10,000 bacteria. At the end of the 5 hours, there are 40,000 bacteria. How many bacteria were present initially?

I was planning to use Y=P(O)e^kt
but I'm not sure how to set it up.
