A tank initially contains salt in the pores if inert material and 10 gallons of fresh water. The salt dissolves at a rate per minute 2 times the difference between 3 lbs/gallon (concentration of a saturated solution) and the concentration of the brine. 3 gallons of fresh water per minute enters the tank. How much salt dissolves in 15 minutes?
