A tank contains 8 L (liters) of water in which is dissolved 32 g (grams) of salt. A solution containing 2 g/L of the brine flows into the tank at a rate of 9 L/min, and the well-stirred mixture flows out at a rate of 5 L/min.
A) Find an equation to model this system using A to represent the amount of salt in the tank and t to represent minutes.
B) Find the amount of salt in the tank after 4 minutes.
