A tank initially contains 50 gal of brine in which there is 10 lb of salt. Starting t = 0, a brine containing 2 lb of dissolved salt per gal flows into the tank at the rate of 5 gal/min. The mixture is kept uniform by stirring and the well-stirred mixture flows out at the rate of 3 gal/min. How much salt is in the tank at any time t> 0 ?
