Question

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 an inch.

bond paper has a thickness of 1/4 inch over one hundred pages

write an equation for the width of the book, y, if it has x hundred pages printed on bond paper

Answer 1

y = 1/2 + 1/4*x

Step-by-step explanation:

Given that the front cover has a thickness of 1/4 an inch and back cover also has a thickness of 1/4 an inch, then, the addition of both gives to the book thickness of 1/4 + 1/4 = 1/2 inch, despite how many pages it has.

Given that for every hundred pages a thickness of 1/4 inch is added to the book, then the equation is:

y = 1/2 + 1/4*x

where y refers to the width of the book, and x refers to every hundred pages printed on bond paper. Y is measured in inches.
