A tank contains 50kg of salt and 2000L of water. A solution of a concentration 0.0125kg of salt per liter enters a tank at the rate 5L/min. The solution is mixed and drains from the tank at the same rate. Let y be the number of kg of salt in the tank after t minutes. Write the differential equation for this situation part 1. dy/dt = part 2. y(0)=
