Problem Analysis

We are given that Lara made 18 bookmarks for books, while Svetlana made 20 bookmarks more than Lara. We need to find the total number of bookmarks made by both girls together.

Solution

To find the total number of bookmarks made by both girls, we need to add the number of bookmarks made by Lara and the number of bookmarks made by Svetlana.

Let's denote the number of bookmarks made by Lara as L and the number of bookmarks made by Svetlana as S.

We are given that Lara made 18 bookmarks, so L = 18.

We are also given that Svetlana made 20 bookmarks more than Lara, so S = L + 20.

To find the total number of bookmarks made by both girls, we need to calculate L + S.

Let's substitute the values of L and S into the equation:

L + S = 18 + (18 + 20)

Simplifying the equation:

L + S = 18 + 38

L + S = 56

Therefore, the total number of bookmarks made by both girls together is 56.

Answer

The total number of bookmarks made by Lara and Svetlana together is 56.
