Problem Analysis

To find the cost of each type of ball, we need to set up a system of equations based on the given information. Let's assume the cost of a small ball is x rubles, and the cost of a large ball is 3x rubles. We know that 3 large balls and 2 small balls were purchased for a total of 33 rubles. We can set up the following equation:

3(3x) + 2x = 33

Now, let's solve this equation to find the value of x and then calculate the cost of each type of ball.

Solution

Let's solve the equation to find the value of x:

9x + 2x = 33

11x = 33

x = 33 / 11

x = 3

The cost of a small ball (x) is 3 rubles.

Since the cost of a large ball is 3 times the cost of a small ball, the cost of a large ball is:

3 * 3 = 9 rubles

Therefore, a small ball costs 3 rubles, and a large ball costs 9 rubles.

Answer

The cost of each type of ball is as follows: - A small ball costs 3 rubles - A large ball costs 9 rubles
