Can you tell me the answer to this math word problem?

At 8:00 A.M., you told your best friend a deep, dark secret. Then, within 15 minutes, your best friend told two other people. Then within the next 15 minutes, those two people each told two other people. This continued all day long, with every person telling two other people who hadn't been told every 15 minutes. How many people would know your deep, dark secret by 3:00 P.M.?

I just need the answer of how many people know. No need for work.
