Problem 3. A very large tank initially contains 100L of pure water. Starting at time t = 0 a solution with a salt concentration of 0.7kg/L is added at a rate of 7L/min. The solution is kept thoroughly mixed and is drained from the tank at a rate of 5L/min. Answer the following questions. 1. Let y(t) be the amount of salt (in kilograms) in the tank after t minutes. What differential equation does y satisfy? Use the variable y for y(t). Answer (in kilograms per minute): dy dt
