Question

A new book is being planned. It will have 24 pages of introduction. Then it will have c 12-page chapters and 48 more pages at the end.Write a rule that represents the total number of pages p in the book as a functional of the number of chapters.Suppose the book has 25 chapters.How pages will it have?

Answer 1

Let the number of pages be y and the number of chapters be x, then y = 24 + 12x + 48 = 12x + 72

y = 12x + 72

If the book has 25 chapters, the number of pages will be y = 12(25) + 72 = 300 + 72 = 37 pages.
