Problem Analysis

We have purchased 4 identical chairs and a chair that is three times more expensive than the chairs. We need to determine the price of the chair.

Solution

Let's assume the price of each chair is x. According to the given information, the total cost of the chairs is 600 rubles. Since we bought 4 chairs, we can write the equation:

4x + 3x = 600

Simplifying the equation, we get:

7x = 600

To find the value of x, we divide both sides of the equation by 7:

x = 600 / 7

Evaluating the expression, we find:

x ≈ 85.71

Therefore, the price of each chair is approximately 85.71 rubles. Since the chair is three times more expensive than the chairs, the price of the chair is:

3 * 85.71 ≈ 257.14 rubles.

So, the price of the chair is approximately 257.14 rubles.

Answer

The price of the chair is approximately 257.14 rubles.
