Question

Dr. Chandler wants to print copies of

his thesis in hardcover book format. He
could use Washington Printing, paying a
setup fee of $41 and $6 for every book
printed. Or, he could go through Fairfax
University, paying an up-front fee of
$32 and $9 per book. For how many
books will the costs be the same? How
much is that?

Answer 1

For 3 books, costs are the same

$59

Explanation:

x = number of books

$41 + ($6/book)(x) = $32 + ($9/book)(x)

41 - 32 = 9x - 6x

9 = 3x

x = 9/3 = 3

41 + 6(3) = 32 + 9(3) = $59
