The maximum water level ranges from 73 inches to 97 inches, and the minimum water level also ranges from 73 inches to 97 inches.
To represent the maximum and minimum water levels for the dock, we can use the equations |w + 85| = 12 and |w - 85| = 12.
The first equation, |w + 85| = 12, represents the maximum water level.
It indicates that the water level w can be 12 inches above or below 85 inches, resulting in a range from 73 inches to 97 inches.
The second equation, |w - 85| = 12, represents the minimum water level. It indicates that the water level w can be 12 inches below or above 85 inches, resulting in a range from 73 inches to 97 inches as well.
