(1 point) A very large tank initially contains 100L of pure water. Starting at time t = 0 a solution with a salt concentration of 0.6kg/L is added at a rate of 5L/min. The solution is kept thoroughly mixed and is drained from the tank at a rate of 3L/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). dy dt Answer (in kilograms per minute): 2. How much salt is in the tank after 30 minutes?
