A small publishing company is planning to publish a new book. The production costs will include onetime fixed costs (such as editing) and variable costs (such as printing). There are two production methods it could use. With one method, the one-time fixed costs will total $23,197, and the variable costs will be $18.50 per book. With the other method, the one-time fixed costs will total $37,783, and the variable costs will be $12 per book. For how many books produced will the costs from the two methods be the same?
2244 books
