Fernando built a robot to filter air and water efficiently. He expects the robot to filter more than 512
liters of air and water while using less than 9 Joules of energy.
A represents the number of minutes the robot filters air, and W represents the number of minutes
the robot filters water.
21 A + 14W > 512 represents the number of minutes the robot filters air and water to filter more
than 512 liters of air and water
0.36 A + 0.6W < 9 represents the number of minutes the robot filters air and water while using
less than 9 Joules of energy.
Does the robot meet both of Fernando's expectations by filtering air for 15 minutes and filtering
water for 5 minutes?
