Question 6

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 < 49 represents 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?
