1. The problem statement, all variables and given/known data This problem is driving me crazy because it seems so simple yet I can't get the right answer. We're looking for how long it takes for the biomass of halibut to get within 10% of carrying capacity (look below). 2. Relevant equations We have to use this formula: y(t)= 8x10^7/(1+3e^-.71t) 3. The attempt at a solution I don't even know. How do I find t without knowing y(t)? Everyone I've asked so far has said, "Just plug in". Just plug in what? I know M needs to be changed, and that's about it. The correct answer is 4.6. I'm so confused. Help please?
