A 200-liter tank is initially full of fluid in which there is dissolved 40 grams of a certain chemical. Fluid containing 50 grams per liter of this chemical flows into the tank at the rate of 5 liters/minute. The mixture is kept uniform by stirring, and the stirred mixture simultaneously flows out at the rate of 7 liters/minute. How much of the chemical in grams is in the the tank when it is only half full?
