Problem Analysis

We are given that in a store, three carpets were sold. The first carpet was priced at 3962 lei, and the second carpet was 1458 lei cheaper than the first one. We need to find the price of the third carpet, which was twice as expensive as the second carpet.

Solution

Let's denote the price of the second carpet as x lei. According to the given information, the first carpet was 1458 lei more expensive than the second carpet. Therefore, the price of the first carpet can be expressed as x + 1458 lei.

We are also told that the third carpet was twice as expensive as the second carpet. Therefore, the price of the third carpet can be expressed as 2x lei.

To find the price of the third carpet, we need to solve the equation 2x = x + 1458.

Solving the Equation

To solve the equation 2x = x + 1458, we can subtract x from both sides of the equation:

2x - x = x + 1458 - x

This simplifies to:

x = 1458

Therefore, the price of the second carpet (x) is 1458 lei.

Finding the Price of the Third Carpet

Now that we know the price of the second carpet is 1458 lei, we can find the price of the third carpet, which is twice as expensive as the second carpet. Therefore, the price of the third carpet is:

2 * 1458 = 2916 lei

So, the price of the third carpet is 2916 lei.

Answer

The price of the third carpet is 2916 lei.
