A small publishing company is planning to publish a new book. The production costs will include one-time 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 $ 76,972, and the variable costs will be $9.25
per book. With the other method, the one-time fixed costs will total $13,372, and the variable costs will be $22.50 per book. For how many books produced will
the costs from the two methods be the same?
