Problem Analysis

Afanasiy read a book in three days. On the first day, he read 8 pages. On the second day, he read 3 pages more than on the first day. On the third day, he read 7 pages less than on the second day. We need to determine the total number of pages in the book.

Solution

Let's break down the information given: - On the first day, Afanasiy read 8 pages. - On the second day, he read 3 pages more than on the first day. - On the third day, he read 7 pages less than on the second day.

To find the total number of pages in the book, we need to calculate the sum of the pages read on each day.

Let's denote: - The number of pages read on the first day as x. - The number of pages read on the second day as x + 3 (3 pages more than the first day). - The number of pages read on the third day as (x + 3) - 7 (7 pages less than the second day).

To find the total number of pages, we need to sum up the pages read on each day:

Total pages = x + (x + 3) + [(x + 3) - 7]

Simplifying the equation:

Total pages = 3x - 1

Now, we can solve for x by substituting the given information that Afanasiy read 8 pages on the first day:

8 = 3x - 1

Solving for x:

3x = 9

x = 3

Now, we can substitute the value of x back into the equation to find the total number of pages:

Total pages = 3(3) - 1 = 9 - 1 = 8

Therefore, there are 8 pages in the book.

Answer

There are 8 pages in the book Afanasiy read.
