I need help in solving the following solution.
The Gompertz model has been used to model population growth.
dy/dt = -ryln(y/k), where r = 0.67 per year, K = 36500 kg,

Use the Gompertz model to find the predicted value of y(4) .

TIA.

Have you tried solving the differential equation? Do you have any ideas about how you might try to solve it? I'll give you a hint: t does not appear explicitly, and it is a first-order, homogeneous (but nonlinear) equation for y(t). Does this give you any ideas?
