Tank A contains 25 lbs of salt dissolved in 100 gal of water. Tank B contains 40 lbs of salt dissolved in 100 gal of water. The mixture from tank A is pumped to tank B at the rate of 30 gal per hr, while the mixture from tank B is pumped to tank A at the same rate. Assume that the mixture in each tank is uniform by stirring. Let A(t ) and B(t ) be the amount of salt in tanks A and B after t hours, respectively.
(a) Draw a two-compartment model for A(t ) and B(t ). (b) Use the initial conditions A(0) = 25 and B(0) = 40 to solve for A and B. (c) What are the equilibrium values of A and B? 18. (
