Given the following figure and information, solve for the following: A. The working matrix of the system of differential equations; B. The mathematical model for the amt. of salt in each of the tanks at time, t; C. The amount of salt in tank A at t = 25 minutes if initially, 100 lbs of salt is dissolved in tank A and 50 lbs in tank B and assuming that tank C contains fresh water and that the mixture in each tank is kept uniform by stirring. 4 gal/min Pure HO 4 gal/min 100 gal 150 gal 100 gal A B C 4 gal/min 4 gal/min
