A 200-gal tank is half full of distilled water. At time t = 0, a solution containing 0.5 lb /gal of concentrate en-ters the tank at the rate of 5 gal/ min, and the well-stirred mixture is withdrawn at the rate of 3 gal/min. a. At what time will the tank be full? b. At the time the tank is full, how many pounds of concentrate will it contain?
