A tank contains 40 gal brine for which the concentration is initially 3 lb/gal of salt. A brine solution is pumped into the tank at the rate of 5 gal/min. and the mixture, kept uniform by stirring, runs out at the same rate. If the concentration of the solution flowing in is 2 lb/gal, a) determine the amount of salt in the tank at anytime t, b) how much salt is present after 10 min? c) after a long time?
