Researchers have created artificial red blood cells. These artificial red blood cells are cleared from circulation by a first-order reaction with a half- life of 3 hours. If it takes one hour to get an accident victim, whose red blood cells have been replaced with artificial red blood cells, to a hospital, what percentage of the artificial red blood cells remain in the victim when the victim reaches the hospital?
