A tank contains 90 kg of salt and 2000 L of water. Pure water enters a tank at the rate 6 L / min. The solution is mixed and drains from the tank at the rate 8 L / min.

Let y be the number of kg of salt in the tank after t minutes.

The differential equation for this situation would be:

dy/dt=

y(0)=
