A tank originally contains 130 liters of water with 10 grams of salt in solution. Beginning at t = 0, water containing 0.6 grams of salt per liter flows into the
tank at a rate of 3 liters per minute and the uniform mixture drains from the tank at a rate of 3 liters per minute. Letting t be time in minutes and Q be the
amount of salt in the tank at time t measured in grams, formulate an initial value problem modeling the amount of salt in the tank at any time.
