A tank contains 50 kg of salt and 1000 L of water. A solution of a concentration 0.025 kg of salt per liter enters a tank at the rate 9 L/min. The solution is mixed and drains from the tank at the same rate.
(a) What is the concentration of our solution in the tank initially?
concentration = (kg/L)
(b) write down the differential equation which models the Amount y of salt in the tank:
dydt=
(c) Find the amount of salt in the tank after 2.5 hours.
amount = (kg)
(d) Find the concentration of salt in the solution in the tank as time approaches infinity.
concentration = (kg/L)
