yct) = y Problem Three (10 pts): A tank contains 1000L of pure water. Brine that contains .05 kg of salt per liter of water enters the tank at a rate of 5L/min. Brine that contains .04 kg of salt per liter of water enters the tank at a rate of 10L/min. The solution is kept thoroughly mixed and drains from the tank at a rate of 15 L/min.
