The air in a room with volume 180 m3 contains 0.4% carbon dioxide initially. Fresher air with only 0.05% carbon dioxide flows into the room at a rate of 2 m3/min and the mixed air flows out at the same rate. Find the percentage p of carbon dioxide in the room as a function of time t (in minutes).
p(t) =
What happens with the percentage of carbon dioxide in the room in the long run?
