Answer 1

300 feet above sea level now

Explanation:

if she went up 500 (+500)

if she started at 200 feet below sea level, (-200)

then,

-200+500= 300

She is at 300 feet above sea level

Answer 2

300 feet above sea level

Explanation:

If she started at 200 feet below sea level, this is equivalent to -200ft. If she went up, you can add 500 to -200, so -200+500 is 300. Her current elevation is 300 feet above sea level.
