One time fixed cost total $15,210. The variable cost will be $11 per book. The publisher will sell the finished product to bookstores at a price of $18.50 per book.

You can put this solution on YOUR website!
Let +C+ = production costs
Let +S+ = income from sales of books
Let +n+ = number of books sold
---------------------------------------
(1) +C+=+11n+%2B+15210+
(2) +S+=+18.5n+
-------------------------
Set +C+=+S+
+11n+%2B+15210+=+18.5n+
+7.5n+=+15210+
+n+=+2028+
----------------
The publisher must sell 2028 books so
that cost = money from sales
