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.
Bond 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.

Question 11

11.

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.
Ledger 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 bond paper.

Question 12

12.

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?

the slope (changing value) would change

the y-intercept (starting value) would change

the slope and y-intercept would change
