Report

An executive conference room of a corporation contains $4500 \mathrm{ft}^{3}$ of air initially free of carbon monoxide. Starting at time $t=0,$ cigarette smoke containing $4 \%$ carbon monoxide is blown into the room at the rate of $0.3 \mathrm{ft}^{3} / \mathrm{min} .$ A ceiling fan keeps the air in the room well circulated and the air leaves the room at the same rate of $0.3 \mathrm{ft}^{3} / \mathrm{min}$. Find the time when the concentration of carbon monoxide in the room reaches $0.01 \%$
