Suzi starts her hike at 220 feet below sea level. When she reaches the end of the hike, she is still below sea level at −107 feet. What was the change in elevation from the beginning of Suzi's hike to the end of the hike? The change was feet.
 

113 feet.

Step-by-step explanation: Even though Suzi was still below sea level at the end of the hike, she still climbed 113 feet higher.

The change will be positive, though, because Suzi was climbing up, not down. Therefore the final answer is 113 feet.

Step-by-step explanation:

Let sea level be our reference point.  Suzi starts at -220 ft and ends up at -107 ft.  The change in elevation is represented by x = |-220 ft - (-107 ft)|, or 113 ft.

y > 1/3x

y < = -x + 4

hope this : )
