The break-even point is the point at which income equals expenses. Ridgemont high school is paying $13,200 for the writing and research of
their yearbook plus a printing fee of $25 per book. If they sell the books for $40 each, how many will they have to sell to break even? Explain.
They need to cover expense of $13200. If printing fee is $25 and they sell the books for $40 each, then that means when selling a book they cover expense of printing plus they earn $15 per book.
So if they earn $15 per book that means they have to sell `13200/15=880` books to break even.
If you want to solve this by using equation the this would look like this:
expenses: $13200 + $25`x` where `x` is number of books sold
