Assignment:
Set up but do not solve a differential equation that models the amount of salt in the tank for the following: A tank, having a capacity of 700 liters, initially contains 3 kilograms of salt dissolved in 100 liters of water. At time t=0, a solution containing 0.4 kilograms of salt per liter flows into the tank at a rate of 3 liters/min and the well stirred moisture flows out at a rate of 2 liters/min. Be sure to define all of your variables.
Provide complete and step by step solution for the question and show calculations and use formulas.
