So we just do cost/number of people=cost per 1 person so (6p)/(3p^2) remember that you can split it up and make ones = times = times times = times 1 times 1=2/p
easy way is remember that (x^m)/(x^n)=x^(m-n) so (6p)(3p^2)=6/(3p=2/p=2p^-1
The answer that you are looking for is 60 . It will take 60 days until there will be 30 million new accounts added to a site. If you divide 30 from .5 you would get 60 so that would be your answer
