A tank contains 200 liters of fluid in which 30 grams of salt is dissolved. Brine containing 2 grams of salt per liter is then pumped into the tank at the rate of 4 liters per minute and the well-mixed solution is pumped out at the same rate. How many grams of salt are there in the tank after 1.30 hours?
