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 has a thickness of $\frac{1}{4}$ of an inch. They have a choice of which type of paper to print the book on.
ABond paper has a thickness of $\frac{1}{4}$ 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.
BLedger paper has a thickness of $\frac{2}{5}$ 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.
CIf 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?
