Brine is a high-concentration solution of salt in water. Brine with salt concentration of 4lb per gallon is allowed to enter a tank that contains 100 gal of pure water at t = 0. The mixture of brine and pure water is kept uniform throw stirring. The stirred mixture flows out of the tank at the rate of 3 gal/min. a) Find the amount of salt in the tank after 20 minutes. b) After how much time there will be 50lb of salt in the tank?
