Question
Two well-mixed tanks are interconnected. Tank A contains 60 grams of salt in 40 liters of water, and Tank B
contains 70 grams of salt in 20 liters of water. A briny solution with concentration 2 gram/L flows into Tank
A at a rate of 7 L/min, while a solution with concentration 3 grams/L flows into Tank B at a rate of 5
L/min. The tanks are connected, so 8 L/min flows from Tank A to Tank B, while 1 L/min flows from Tank B
to Tank A. An additional 12 L/min drains from Tank B. Letting x1 represent the grams of salt in Tank A, and
x2 represent the grams of salt in Tank B, set up the IVP for amount of salt in these two tanks.
