Solve the following word problems. Express all answers in simplest form with the correct units. 4) A tank contains 80 gal of pure water. Brine solution with 2 lb/gal of salt enters at 2 gal/min, and the well-stirred mixture leaves at the same rate. Find a) the amount of salt in the tank after half an hour, b) determine the limiting value for the amount of salt in the tank after a long time, and c) how much time must pass before the amount of salt in the tank reaches 80% of this limiting value
