Mountain climbers call the region above 26,000 feet the Death Zone because the air is too thin for humans. At that altitude, brain cells die, the blood grows thick, the heart speeds up, and the brain can swell - leading to death.
26000 increased by 30 percent =33800=26000 + (30% * 26000 )=26000 + (0.3 * 26000 )=26000 + 7800= 33800
Actually the death Zone is Camp 4 which is 26000 feet height. At that altitude people feel weak and accidents happen.
26000
because you could fall of the hight of a mountain at 26,000 feet above ground
7% of 26000 = 7% * 26000 = 0.07 * 26000 = 1820
70% of 26,000= 70% * 26000= 0.7 * 26000= 18,200
