 <translate> Ernie has three times as many stamps as Peggy, or 3 * 75 = 225 stamps. Bert has 4 times as many stamps as Ernie, or 4 * 225 = 900 stamps. Thus, Peggy would need 900 - 75 = 825 more stamps to have a collection as large as Bert's. So the answer is 825. <yor> Ìlọ́po mẹ́ta ni iye tí Ernie ní ju iye tí Peggy ní lọ, ìyẹn ni pé, 3 * 75 = 225 owó sítáǹbù.
