Problem Analysis

We are given three shelves with books. On the first shelf, there are 42 books. On the second shelf, there are 23 more books than on the first shelf. On the third shelf, there are as many books as on the first two shelves combined, plus 3. We need to find the total number of books on all three shelves.

Solution

Let's break down the problem step by step:

1. On the first shelf, there are 42 books. 2. On the second shelf, there are 23 more books than on the first shelf. So, the second shelf has 42 + 23 = 65 books. 3. On the third shelf, there are as many books as on the first two shelves combined, plus 3. So, the third shelf has (42 + 65) + 3 = 110 books.

To find the total number of books on all three shelves, we add the number of books on each shelf: 42 + 65 + 110 = 217.

Therefore, there are 217 books on the three shelves.

Answer

There are 217 books on the three shelves.
