A tank contains 100 gal of water. Brine enters the tank at the rate of 3 gal/min. The mixture, thoroughly stirred, leaves the tank at the rate of 2 gal/min. If the salt concentration in the brine at the end of 20 minutes is to be 2 lb/gal, what should be the salt concentration in the brine entering the tank?
