Concentration (in mg/ml) in the bloodstream of a certain drug is related to the time t (in minutes) after an injection and can be calculated using y in the equation y = A ln(t) − Bt + C where A, B, and C are positive constants. In terms of A and B, find t at which y (and hence the drug concentration) reaches its maximum. t = ___ min
