Suppose that a large mixing tank initially holds 300 gallons of water in which 50 pounds of salt have been dissolved. Pure water is pumped into the tank at a rate of 3 gal/min, and when the solution is well-stirred, it is then pumped out at the same rate. Determine the differential equation for the amount of salt x(t) in the tank at any timet > 0. dr O A. dt 3. 300 dr O B. dt = 0 100 dr O C. = 3 100 dt dz O D. dt = 0 300 O E. None of the choices
