Answer:
Suzi's elevation in the hike is 37 feet.
Step-by-step explanation:
We are given the following in the question:
Position of Suzi in the starting of hike = 200 feet below sea level
= -200 feet
The negative sign shows below sea level.
Position of Suzi in the end of hike = -163 feet
Change in elevation from the beginning of Suzi's hike to the end of the hike
= Position of Suzi in the end of hike - Position of Suzi in the starting of hike

Thus, Suzi's elevation in the hike is 37 feet.
