The peak is 14,623 ft above sea level. The climber then descends 216 ft to meet a fellow climber. Find the climber's elevation above sea level after meeting the other climber.
14,839 ft above sea level
14,407 ft above sea level
216 ft below sea level
10,340 ft above sea level
assuming the climber reached the peak, we have
14623-216 = ______
