Problem Analysis

To solve this problem, we need to determine the number of models of trucks in Kostya's collection and the total number of models of cars in his collection. We are given that there are 26 models of cars in the collection, which is 17 more than the number of models of trucks.

Solution

Let's assume the number of models of trucks in Kostya's collection is x. According to the problem, the number of models of cars is 17 more than the number of models of trucks. Therefore, the number of models of cars can be represented as x + 17.

We are also given that the total number of models in Kostya's collection is 26. So, the sum of the number of models of cars and the number of models of trucks should be equal to 26.

Based on the above information, we can set up the following equation:

x + (x + 17) = 26

Simplifying the equation, we get:

2x + 17 = 26

Subtracting 17 from both sides, we have:

2x = 9

Dividing both sides by 2, we find:

x = 4.5

Since the number of models of trucks cannot be a decimal, we can conclude that there are no models of trucks in Kostya's collection. Therefore, the number of models of trucks in Kostya's collection is 0.

To find the total number of models in Kostya's collection, we can add the number of models of cars and the number of models of trucks:

Total number of models = Number of models of cars + Number of models of trucks

Total number of models = (x + 17) + x = 2x + 17

Substituting the value of x, we get:

Total number of models = 2(4.5) + 17 = 9 + 17 = 26

Therefore, the total number of models in Kostya's collection is 26.

Answer

Kostya's collection does not have any models of trucks. The total number of models in his collection is 26.
