Question shows below:

(1 point) A very large tank initially contains lOOL of pure water. Starting at time t = 0 a solution with a salt concentration of 0.3kg/L is added at a rate of 6L/mi11. The solution is kept thoroughly mixed and is drained from the tank at a rate of 4L/mi11. Answer the following questions. 1 . Let y(t) be the amount of salt (in kilograms) in the tank after 1' minutes. What differential equation does y satisfy? Use the variable y for 32(3). dy Answer (in kilograms per minute): 5 = 1.8 2. How much salt is in the tank after 20 minutes? Answer (in kilograms): 40_47
