ose that a large mixing tank initially holds 200 gallons of water in which 30 pounds of salt have been dissolved. Pure water is pumped into the tank at a rate of 2 gal/min, and when the solution is well stirred, it is then pumped out at the same rate. Determine a rential equation for the amount of salt A(t) in the tank at time t > 0. What is A(0)? (Use A for A(t).)
