A tank contains 140 gallons of water and 45 oz of salt. Water containing a salt concentration of (1 + and the mixture in the tank flows out at the same rate. sint) oz/gal flows into the tank at a rate of 6 gal/min, The long-time behavior of the solution is an oscillation about a certain constant level. What is this level? What is the amplitude of the oscillation? Round the values to two decimal places. Oscillation about a level = Amplitude of the oscillation = OZ. OZ.
