Question

suzi starts her hike at 210 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?

Answer 1

she is at 98 above sea level

Explanation:

you subtract the lesser absolute value from the greater absolute value . use the sign of the integer with the greater absolute value

Answer 2

Suzi starts out her trek below sea level at an elevation of -210ft. You know this because the question reads below sea level. When she gets to the end of her hike she is still below sea level at -107ft. We can use simple math by subtracting 107 from 210 to figure that she has traveled a 103ft up in elevation. She is still below sea level so we still see the noted elevation as a negative number.
