Two band mates have only 7 days to spread the word about their next performance. jack thinks they can each pass
out 100 fliers a day for 7 days, and they will have done a good job in getting the news out. meg has a different
strategy. she tells 10 of her friends about the performance on the first day and asks each of her 10 friends to each
tell a friend on the second day and then everyone who has heard about the concert to tell a friend on the third day,
and so on, for 7 days. make an assumption that students are not telling someone who has not already been told.
a. over the first 7 days, meg’s strategy will reach fewer people than jack’s. show that this is true.
