15. COSS MODELING 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.

Let that be x


\\ \rm\Rrightarrow 13200+25x=40x


\\ \rm\Rrightarrow 40x-25x=13200


\\ \rm\Rrightarrow 15x=13200


\\ \rm\Rrightarrow x=13200/15


\\ \rm\Rrightarrow x=880

Answer:

Explanation:

The break-even point is the point at which income equals expenses.

Let that number of books sold be x

Printing costs = 13200 + 25x

Book sale = 40x

At break-even, the printing costs is the same as book sale.

13200 + 25x = 40x

15x = 13200

x = 13200/15 = 880
