A 19000 cubic foot room initially has a radon level of 870 picocuries per cubic foot. A ventilation system is installed that brings in 500 cubic feet of air per hour that contains 7 picocuries per cubic foot, while an equal quantity of the well-mixed air in the room leaves the room each hour. Setup and use a differential equation to determine how long it will take for the room to reach a safe to breathe level of 110 picocuries per cubic foot
