step by step please

Atank contains 50 kg of salt and 1000 L of water. F'ure water enters a tank at the rate 6 Umin. The soiutjon is mixed and (trains from the tank at the rate 3 Umin. (a) Write an initial value problem for the amount of salt, y' in kilograms, at time t in minutes: do _ E = C] (hymn) yiD) = C] Kg. (h) Solve the initial value problem in part (a) ya) = C] kg. (E) Find the amount of salt in the tank after 2 hours amount 2 E] (kg) ([1) Find the concentration of salt in the solution in the tank as time approaches innity. (Assume yourtank is large enough to hold alt the solution.) ooncentration : C] (kgfL)
