Answer: Negative integer is used to indicate the new water level i.e. 2 feet below the dock.

Step-by-step explanation:

Since we have given that

The water level is 3 feet below your dock.

It means the level of water = -3 feet

The tide goes out, and the water level lowers 1 foot

The level of water = -1 feet

A storm surge comes in, and the water level rises 2 feet.

The level of water = +2 feet

According to question, it becomes

$-3-1+2\\\\=-4+2\\\\=-2\ feet$

Hence, Negative integer is used to indicate the new water level i.e. 2 feet below the dock.

We know that that the water level is 3 feet below your deck. (-3)
When the tide goes out, the water level lowers 1 foot. (-1)
A storm surge comes in, the water level rises 2 feet. (+2)

New water level: -3-1+2= -4+2= -2
The new water level is 2 feet below the dock.
