The pacific halibut fishery has been modeled by the differential equation dy dt = ky 1 − y m where y(t) is the biomass (the total mass of the members of the population) in kilograms at time t (measured in years), the carrying capacity is estimated to be m = 9 × 107 kg, and k = 0.75 per year. (a) if y(0) = 2 × 107 kg, find the biomass a year later. (round your answer to two decimal places.)
