Question

Two drivers are exploring the bottom of a trench in the Pacific Ocean. Dominic is at 175 feet below the surface of the ocean and Karen is at 138 feet below the surface represent each quantity by an integer and determine who is deeper in the water

Answer 1

$\huge\boxed{\text{Dominic}}$

In this problem, $0$ represents the sea level. Since Dominic is $175$ feet below the surface (sea level), his current location is at $-175$ feet.

The same concept can be applied to Karen, who is at $-138$ feet.

We need to find who is lower, or farther below $0$. This means the answer is $\boxed{\text{Dominic}}$.
