A large tank is filled to capacity with 300 gallons of pure water. Brine containing 4 pounds of salt per gallon is pumped into the tank at a rate of 3 gal/min. The well-mixed solution is pumped out at a rate 6 gals/min. Find the number A(t) of pounds of salt in the tank at time t. 3 A(t) = (100-1)²-301+3000 lb X How long (in minutes) will it take for the tank to be empty after this process has started? 100 ✓ min
