Answer 2

Calculation of the Total Cost

To find out how much was paid for the chairs and shelves separately, we can set up a system of equations based on the given information.

Let's assume the cost of each chair is x rubles and the cost of each shelf is also x rubles.

According to the given information, the total cost of 3 chairs and 5 shelves is 720,000 rubles. We can express this as an equation:

3x + 5x = 720,000

Simplifying the equation, we get:

8x = 720,000

Now, let's solve for x to find the cost of each chair and each shelf separately.
