Problem Analysis

We are given that a table is 9 times more expensive than a chair, and together they cost 80 rubles. We need to determine the individual prices of the table and the chair.

Solution

Let's assume the price of the chair is x rubles. Since the table is 9 times more expensive than the chair, the price of the table can be expressed as 9x rubles.

According to the given information, the total cost of the table and chair is 80 rubles. We can set up the following equation:

x + 9x = 80

Simplifying the equation, we get:

10x = 80

Dividing both sides of the equation by 10, we find:

x = 8

Therefore, the price of the chair is 8 rubles. Since the table is 9 times more expensive, the price of the table is:

9 * 8 = 72 rubles

So, the chair costs 8 rubles and the table costs 72 rubles.

Answer

The chair costs 8 rubles and the table costs 72 rubles.
