Air containing 0.04% carbon dioxide is pumped into a room whose volume is 6,000 ft3. The air is pumped in at a rate of 3,000 ft3/min, and the circulated air is then pumped out at the same rate. If there is an initial concentration of 0.3% carbon dioxide, determine the subsequent amount A(t), in ft3, in the room at time t. What is the concentration of carbon dioxide at 10 minutes? (Round your answer to three decimal places.)
