A tank initially contains 50 gal of pure water. Brine containing 3 lb of salt per gallon enters the tank at 2 gal/min, and the (perfectly mixed) solution leaves the tank at 3gal/min. Thus, the tank is empty after exactly 50 min.(a) Find the amount of salt in the tank after t minutes.(b) What is the maximum amount of salt ever in the tank?
