A tank initially holds 80 gallons of brine solution containing 1/8 Lb of salt per gallon. At t = 0, another brine solution containing 1 lb of salt per gallon is poured into the tank at a rate of 4 gallons per minute, while the well-stirred mixture leaves the tank at a rate of 8 gallons per minute. Find the amount of salt in the tank when the tank contains 40 gallons of solution.
