Problem Analysis

We are given the following information: - Kostya has 15 toy cars in his collection. - Borya has 5 more toy cars than Kostya. - Vova has 3 fewer toy cars than Borya.

We need to determine: 1. How many toy cars does Borya have? 2. How many more toy cars does Vova have compared to Kostya?

Let's solve this step by step.

Solution

1. To find the number of toy cars Borya has, we add 5 to the number of toy cars Kostya has. - Kostya has 15 toy cars. - Borya has 5 more toy cars than Kostya. - Therefore, Borya has 15 + 5 = 20 toy cars.

2. To find the number of toy cars Vova has, we subtract 3 from the number of toy cars Borya has. - Borya has 20 toy cars. - Vova has 3 fewer toy cars than Borya. - Therefore, Vova has 20 - 3 = 17 toy cars.

Now we can answer the questions: - Borya has 20 toy cars. - Vova has 17 toy cars. - Vova has 3 more toy cars than Kostya.

Answer

Borya has 20 toy cars. Vova has 17 toy cars. Vova has 3 more toy cars than Kostya.
