Mixing Problem Differential Equation (Application)

A large tank is initially filled with 100 L of brine (i.e. salt dissolved in water) in which 1 kg of salt is dissolved. Brine containing 1/2 kg of salt per L is pumped into the tank at a rate of 6 L/min. The well-mixed brine is pumped out of the tank at a slower rate of 4 L/min. Assuming that the tank does not overflow, find the amount of salt (in kg) in the tank after t min (t >= 0). Looking for help with math?
