1 A tank contains 480 gallons of water and 15 oz of salt. Water containing a salt concentration of (1 + sint) oz/gal flows into the tank 2 at a rate of 5 gal/min, and the mixture in the tank flows out at the same rate. 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 = i Amplitude of the oscillation = OZ. OZ.
