Fresh water is poured at a rate of 10 gal/min into a tank A, which initially contains 110 gal of asalt solution with concentration 2 lb/gal. The stirred mixture flows out of tank A at the same rateand into a second tank B that initially contained 100 gal of fresh water. The mixture in tank B isalso stirred and flows out at the same rate. a) Determine an IVP satisfied by the amount of salt in tank A.
b) Find the amount of salt in tank A at any time.
c) Find the IVP satisfied by the amount of salt in tank B.
d) Determine the amount of salt in tank B as a function of time.
