+49 feet

Step-by-step explanation:

The inicial position that Suzie started her hike was 220 feet below sea level, so as this inicial position was negative, let's use the negative sign for it:

Inicial position = - 220 feet

The final position of the hike was 171 feet below sea level, so:

Final position = - 171 feet

So we calculate the change in elevation from the beginning to the end of the hike by making the difference between the final position and the inicial position:

Change in elevation = Final position - Inicial position = - 171 - (-220) = - 171 + 220 = + 49 feet

The change in elevation was + 49 feet (the positive sign indicates that the movement was upwards, in direction to "above sea level")
