8. A tank initially contains 200 L of pure water. Brine with a salt concentration of 0.1 kg/L enters the tank at a rate of 5 L/min, and the mixed solution drains out of the tank at the same rate. (a) Set up a differential equation that models this situation, where y(t) is the amount of salt in the tank after t minutes. (b) Solve this differential equation to find y(t), the amount of salt in the tank after t minutes.
