The diver descends to the bottom in three steps of 12 feet each.
Since it is a descent below the sea level, each step = -12 feet
Therefore:
Three Steps of 12 feet each = 3(-12) feet
We can then conclude that the diver's change in elevation
[tex]\begin{gathered} =3\left(-12\right) \\ =-36\text{ feet} \end{gathered}[/tex]The diver's change in elevation is -36 feet.
