To find : a rule that represents the number of pages p in the book as a function of the number of chapters and the number of pages of book which has 25 chapters.
Answer to Problem 18PPE
p=12c+ 72
Explanation of Solution
Given information: A new book will have 24 pages of introduction. It will have c 12-page chapters and 48 more pages at the end.
Calculation:
Number of pages of the book is represented by p and number of chapters of the book is represented by c.
Each chapter has 12 pages, so c chapters have 12c pages.
The book will have 24 pages of introduction and 48 more pages at the end.
Therefore, total number of pages in the book is 24+ 12c+ 48, that is 12c+ 72.
Thus, rule that represents the number of pages p in the book as a function of the number of chapters is
p=12c+ 72
