step by step please

Atank contains 90 kg of salt and 2000 L of water. A solution of a concentration 0.0225 kg of salt per liter enters a tank at the rate 10 mnin. The solution is mixed and drains from the tank at the same rate. (a) What is the concentration of our solution in the tank initially? concentration = C] (kge'L) (b) Set up an initial value problem for the quantity y, in kg. of salt in the tank at time t minutes. % = [:] (Karmin: at\") = C] (Kg) (1:) Solve the initial value proolem in pan ([1). 31(3) = E] ([1) Find the amount Of salt in the tank after 2 i'IOUfS. amount = E] (kg) (e) Find the concentration of salt in the solution in the tank as time approaches innity. concentration = C] (kge'L)
