Problem Analysis

To solve this problem, we need to determine the number of tables and chairs purchased for a school. We are given that there are 220 tables and the number of chairs is 9 times greater than the number of tables. We need to find the number of tables and chairs purchased.

Solution

Let's assume the number of tables purchased is x. According to the problem, the number of chairs is 9 times greater than the number of tables. Therefore, the number of chairs can be represented as 9x.

To find the values of x and 9x, we can set up the following equation:

x + 9x = 220

Simplifying the equation:

10x = 220

Dividing both sides of the equation by 10:

x = 22

Therefore, the number of tables purchased is 22, and the number of chairs purchased is 9 times greater, which is 9 * 22 = 198.

Answer

The school purchased 22 tables and 198 chairs.
