A swimming pool is initially filled with 500 m3 of water with a chlorine concentration of 10 g/m³. Water containing 50 g/m3 of chlorine flows into the pool at a rate of 5 m3 per minute. The well-mixed water in the pool is drained away at the same rate. Find the amount of chlorine in the pool at any time t > 0. Select the correct response: Q(t) = 25000 – 20000 e-t %3D | Q(t) = 25000 – 20000 e-t/100 Q(t) = 25000 - 25000 e-t/100 Q(t) = 20000 – 25000 e-t/100
