Amy and three friends launch a new website. Each of the four friends e-mails the web address to three new friends. These new friends forward the web address to three more friends. If no one receives the e-mails more than once, how many people will receive the web address in the second wave of e-mails?

I am pretty sure it would be 10 because you add 3 to the 4 friends who started it and then those 3 sent out one e-mail each. So it would be a total of 10.
