A tank contains 240 gallons of water and 50 oz of salt. Water containing a salt concentration of =(1 + -sint) oz/gal flows into the tank at a rate of 8 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 OZ. Amplitude of the oscillation = i OZ
