Transcribed Image Text:Two tanks are interconnected. Tank A contains 80 grams of salt in 20 liters of water, and Tank B contains 60
grams of salt in 40 liters of water.
A solution of 4 gram/L flows into Tank A at a rate of 10 L/min, while a solution of 2 grams/L flows into Tank
B at a rate of 6 L/min. The tanks are well mixed.
The tanks are connected, so 11 L/min flows from Tank A to Tank B, while 1 L/min flows from Tank B to
Tank A. An additional 16 L/min drains from Tank B.
Letting a represent the grams of salt in Tank A, and y represent the grams of salt in Tank B, set up the system
of differential equations for these two tanks.
