Nadia built a robot to filter air and water efficiently. She expects the robot to filter more than 343 liters of air and water while using less than 49 Joules of energy. 12A+8W > 343 represents the number of minutes the robot filters air A and water W to filter more than 343 liters of air and water. 3A+4W < 49presents the number of minutes the robot filters air and water while using less than 49 Joules of energy. Does the robot meet both of Nadia's expectations by filtering air for 20 minutes and filtering water for 15 minutes?
