1. The problem statement, all variables and given/known data Biologists stocked a lake with `400` fish and estimated the carrying capacity (the maximal population for the fish of that species in that lake) to be `6900`. The number of fish doubled in the first year. 2. Relevant equations 3. The attempt at a solution I know how to do everything in this problem once I find little k. Only issue is...I can't find little k. I thought it would be the ln(2) = .693, but it's .757, and I can't figure out how that answer got there. Once I can find k, I can do the rest easily.
