suzi starts her hike at a elevation if -225 below sea level. When she reaches the end of the hike, she is still nelow sea level at -127 feet. What was the vhange in elevation from the beginning of Suzi's hike to the end of the hike?
There are a couple different ways to get this answer. You could: A. Subtract 127 from (positive) 225, to get the height difference. Or... B. Subtract the starting height from the ending height (-127 - (-225)) which would also give you the height difference.
