Cоnsider а 1000 gаllоn tаnk that is half-full оf fresh water. A brine containing 5 lb/gal of salt is added to the tank at a rate of 2 gal/min. The tank is constantly stirred to ensure a well-mixed solution. This solution drains from a hole in the bottom of the tank at a rate of 1 gal/min. Part A -- 3 points Does the water level in the tank rise (causing overflow) or fall (leaving a fully empty tank)? Part B -- 4 points How many minutes does it take for the tank to either overflow or empty? Part C -- 20 points Let (x(t)) represent the amount of salt in the tank (in pounds) at a given time (in minutes). Write and solve an IVP that describes (x(t)). Part D -- 5 points How many pounds of salt are in the tank when it either overflows or empties?
