Is it logistic? Does it say so? Otherwise treat it as some other random differential equation that you have to integrate and find the solution for yourself. There was a Ch 6 Test question very similar to this one that MANY people missed. But not everyone. So someone's got to speak up!
I don't think this is a logistic problem. Iremember one like this on the Chapter 6 test because I missed it haha. However, I think when it says at a rate proportional to 600-p that means you make the equation (the one that you write up from the problem) equal to 600-p, but I'm not 100% sure. Sorry, if I'm wrong!
The way I did was I made dP/dt equal to (600-P)k, since when growth is proportional to population the differential equation is equal to Pk. Once you have the differential equation dP/dt=(600-P)k you can integrate the equation. Solve for A and k by plugging in the information given. I got a reasonable answer for this one, so I think should work.

i need help on this prblem too
i don't know what it means by a rate proportional to 600-p

thanks
i did what daryl did and got around 25 but i already have that answer...
nvm i got it
watch out for the negative signs.. if you're still reading this blog because that's what made me confused at first
