If all I have given is that(adsbygoogle = window.adsbygoogle || []).push({});

1. Bacteria grows at a rate proportional to it's size.

2. It doubles in 2 days.

3. At 10 days, population is 1000.

I'm not given the initial bacteria count, I need help setting up the equation.

I did:

dy/dt = ky => dy/y = kdt => lny= kt + c => y=e^(kt) + c

y(10)= 1000 = e^(10k) + c

But I'm lost how to complete this. Any idea?
