Hailey went hiking she started the hike at the elevation of 243 feet she climbed down 782 feet when she was ready to leave she climbed back up 118 feet what was haileys elevation at the end of the hiking trip
If she started at 243 feet, subtract 782 feet which is -539 feet. Then add 118 feet which is -421 feet. This is how my sister did it so I hope it helps!
