(Current elevation: -225 feet )

Answer 1

Current Position of Suzi below Level = -225 Feet

Now, Suzi Started her Hike

Position of Suzi after taking Hike from her initial Position= -127 feet

The change in elevation from the beginning of suzi's hike to the end

                  = -127 -(-225)

                  = -127 +225

                  = 98 feet

The change in elevation from the beginning of suzi's hike to the end=98 feet
