Question

Suzi starts her hike at 275 feet below sea level. When she reaches the end of the hike, she is still below sea level at −135 feet. What was the change in elevation from the beginning of Suzi's hike to the end of the hike?

Answer 1

140

Explanation:

Hi there!

This problem may seem tricky because of the negative sea level, os let’s set up an equation.

`-275+x=-135` where x = the change in elevation.

Using orders of operations, add 275 to both sides and you will end with

x = 140

Her change in elevation is 140 feet.

I hope this helps!
