will give medal!! Suppose your friend starts a rumor by telling you some juicy gossip Sunday night. On Monday, one of you shares the gossip with 2 more friends. The next day, they each share the rumor with 2 of their friends, so 4 more people hear the rumor on Tuesday. On Wednesday, those people each share the rumor with 2 of their friends, so now 8 more people have heard the rumor. If the rumor continues to spread this way, how many people will hear the rumor on Saturday?
