Apublisher 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. 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. 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. 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?
