A tank can hold up to 2500 liters of liquid. The tank initially contains 1000 liters of a brine solution with 50kg of salt. A brine solution containing .025 kg/l of salt flows into the tank at a rate of 40 liters per minute and the well mixed solution is pumped out at a rate of 25 liters per minute. At the moment the tank overflows, how much salt is in the solution
