Problem Analysis

We are given the following information: - There are 36 books on the first shelf. - The second shelf has 7 fewer books than the first shelf. - The third shelf has a number of books equal to the sum of the books on the first and second shelves.

We need to find the total number of books on all three shelves.

Solution

Let's break down the problem step by step:

1. Number of books on the second shelf: - The second shelf has 7 fewer books than the first shelf. - So, the number of books on the second shelf is 36 - 7 = 29 books. 2. Number of books on the third shelf: - The third shelf has a number of books equal to the sum of the books on the first and second shelves. - The number of books on the first shelf is 36, and the number of books on the second shelf is 29. - So, the number of books on the third shelf is 36 + 29 = 65 books. 3. Total number of books on all three shelves: - To find the total number of books on all three shelves, we need to add the number of books on each shelf. - The number of books on the first shelf is 36, the number of books on the second shelf is 29, and the number of books on the third shelf is 65. - So, the total number of books on all three shelves is 36 + 29 + 65 = 130 books.

Therefore, there are a total of 130 books on the three shelves.
