A super large tank was initially filled with brine solution of 20 liters. At some point, fresh water starts to flow in at a rate of 8 liters per minute, and the well mixed solution flows out at half of the rate.
Part I Set-up an Initial Value Problem to describe the above problem using to represent the amount of salt in the tank t minutes after the process started. There was certain amount of salt in the tank initially, use to represent the initial amount.
