Nadia built a robot to filter air and water efficiently. she expects the robot to filter more than 343 L of air and water while using less than 49 Joules of energy 12A + 8W is greater than 343 represents the number of minutes the robot filters air A and water W to filter more than 343 L of air and water 3A + 4W is less than 49 represents the number of minutes the robot filters air and water while using less than 49 Joules of energy. does a robot meet both of nadias expectations by filtering air for 20 minutes and filter water for 15 minutes
