I'd say best thing to do here first is to just consider the amount of money Sarah will make on each single copy. Don't take into account the overall total of $600 for the research an writing of the newspaper.

-She is selling the paper at $1.50 per copy.
-It will cost her $0.90 to print and mail each copy.
So, just taking into account these alone, she will make a $0.60 profit on each newspaper she sells.

So, we now need to find out the number of copies she needs to sell to cover the $600 expense, making a profit of $0.60 on each copy. Let 'x' be this number.

So,$$0.60x = 600$$
$$x = \frac{ 600 }{ 0.60 }$$, which you can work out to give you your answer. Good Luck! :)
