Suppose you call the first two friends at 12:05 and you are satisfied because youve shared your secret, so you dont tell anybody else. Unfortunately, none of your friends can keep a secret. Like you, they just need to tell two friends, but then each of those friends needs to tell two friends, and so on.

Write an equation to find the Number of people told for any 5-minute interval in Scenario B.

12:00	0	0	1
12:05	1	2	3
12:10	2	6	7
12:15	3	14	15
12:20	4	30	31
12:25	5	62	63
12:30	6	126	127
12:35	7	254	255
12:40	8	510	511
12:45	9	1022	1023
12:50	10	2046	2047
12:55	11	4094	4095
