Question

a new book is being planned it will have 24 pages of introduction that it will have 12-page chapters and 48 more pages at the end write a rule that represents the total number of pages in the book as a function of the number of chapters suppose it has 25 chapters How many 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.
