3. At time t = 0, a tank contains 25 pounds of salt dissolved in 50 gallons of water. Then a brine solution containing 1 pounds of salt per gallon of water is allowed to enter the tank at a rate of 2 gallons per minute and the mixed solution is drained from the tank at the same rate. a) How much salt is in the tank at an arbitrary time t? b) How much salt is in the tank after 25 minutes? c) As time goes by, what will the amount of salt in the tank approach?
