A bacteria culture grows with constant relative growth rate. After 2 hours there are 800 bacteria and after 8 hours the count is 70,000.

All I need is the formula for the bacteria's growth, then I can answer the other questions on my own.

I don't even know where to start. I have worked with ones where it gives the initial value and how much hourly they grow. Our teacher hasn't explained this one.

Thanks for any help.

If you could explain how you got the formula, I would really appreciate it.
