Question 10
10.
A publisher wants to figure out how thick their new book will be. The book has a front cover and a back cover, each of which have a thickness of \frac{1}{4} of an inch. They have a choice of which type of paper to print the book on.
If they instead chose front and back covers of thickness \frac{1}{3} of an inch,
how would this change the equations in the previous two parts?
