III. A tаnk initiаlly cоntаins 800 liters оf pure water. Brine cоntaining 0.2 kg of salt per liter enters the tank at the rate The well-mixed solution leaves the tank at the rate Assume that the tank is large enough to hold the increasing volume of liquid. Let = the amount of salt in the tank at time , measured in kilograms Determine the volume of solution in the tank. Determine the rate at which salt enters the tank and the rate at which salt leaves the tank. Set up the initial-value problem satisfied by . Solve the initial-value problem and determine the concentration of salt in the tank at time .
