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 1/4 of an inch. They have a choice of which type of paper to print the book on. 1. Bond paper has a thickness of 1/4 inch per one hundred pages. Write an equation for the width of the book, y, if it has x hundred pages, printed on bond paper.
2. Ledger paper has a thickness of 2/5 inch per one hundred pages. Write an equation for the width of the book, y, if it has x hundred pages, printed on ledger paper.
3. If they instead chose front and back covers of thickness 1/3 of an inch, how would this change the equations in the previous two parts?
