Question

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 22756, and the variable costs will be 20 dollars per book. With the other merhod, the one-time fixed costs will total $42408 and the varable costs will be $11.50 per book. For how many books produced will the costs from the two methods be the same?

Answer 1

22756 + 20B = 42408 +11.50B

8.5B = 42408-22756 = 19652

B = 19652/8.5 = 2312 books will make the costs equal for the two production methods
