Problem Analysis

We are given the information that notebooks were purchased for a total of 48 rubles at a price of 8 rubles each, and that identical pencils were purchased for a total of 18 rubles. We need to determine the price of one pencil and the number of pencils and notebooks purchased.

Solution

Let's assume the price of one pencil is x rubles.

From the given information, we know that the total cost of the notebooks is 48 rubles, and each notebook costs 8 rubles. Therefore, the number of notebooks purchased can be calculated by dividing the total cost by the cost of each notebook:

Number of notebooks = Total cost of notebooks / Cost of each notebook = 48 rubles / 8 rubles = 6 notebooks. Similarly, the total cost of the pencils is 18 rubles. Since the price of each pencil is x rubles, the number of pencils purchased can be calculated by dividing the total cost by the price of each pencil:

Number of pencils = Total cost of pencils / Price of each pencil = 18 rubles / x rubles.

Now we have two equations: 1. Number of notebooks = 6 2. Number of pencils = 18 / x

To find the value of x, we need to solve these equations simultaneously.

Solving the Equations

We can substitute the value of the number of notebooks from equation 1 into equation 2:

6 = 18 / x

To solve for x, we can cross-multiply:

6x = 18

Now, divide both sides of the equation by 6:

x = 18 / 6 = 3 rubles.

Therefore, the price of one pencil is 3 rubles.

Since the number of notebooks is given as 6, the number of pencils purchased will also be 6, as the number of pencils and notebooks is the same.

Answer

The price of one pencil is 3 rubles, and the number of pencils and notebooks purchased is 6 each.
