Calculating the Price of a Notebook

To calculate the price of a notebook, we can use the given information that a notebook costs 18 rubles, which is cheaper than 8 exercise books. Additionally, the total cost of 8 exercise books is the same as the cost of 2 notebooks.

Let's denote the price of a notebook as x and the price of an exercise book as y.

Equations Based on Given Information

We can form the following equations based on the given information: 1. The price of a notebook is 18 rubles: x = 18. 2. The cost of 8 exercise books is the same as the cost of 2 notebooks: 8y = 2x.

Solving for the Price of a Notebook

We can use the second equation to solve for the price of a notebook: 8y = 2x 8y = 2 * 18 8y = 36 y = 36 / 8 y = 4.5

So, the price of an exercise book is 4.5 rubles.

Therefore, based on the given information, the price of a notebook is 18 rubles.
