Question

Choose a strategy or a combination of strategies to solve the problem. Alicia forwards an e-mail to 2 of her friends. After 10 minutes, each of those 2 friends forwards the message to 2 more friends. If the message is forwarded like this every 10 minutes, how many people will have received Alicia’s e-mail after 40 minutes?

Answer 1

62 people after 40 minutes.
Multiply the previous number by 2 and add that to the total of recipients
0 minutes = 2. 10 minutes (2+4) =6. 20 minutes (2+4+8) = 14. 30 minutes (2+4+8+16)= 30. 40 Minutes (2+4+8+16+32) = 62
