Dr. Fischer just got her PhD, and she wants to print copies of her thesis in hardcover book
format. She could use Weston Printing, paying a setup fee of $40 and $4 for every book printed.
Alternately, she could go through Newberry University, paying an up-front fee of $30 and $6 per
book. It turns out that, given the number of books Dr. Fischer wants to print, the two options
cost the same amount. How many books is that and what is the cost?
