Calculation of Price Difference

To calculate the price difference between the notebook and the book, we need to know the price of the notebook and the price of the book. According to the information provided, the notebook costs 8 rubles, and the book is four times more expensive than the notebook.

Let's calculate the price of the book:

Price of the book = Price of the notebook * 4

Using the given information, we can substitute the value of the notebook price into the equation:

Price of the book = 8 rubles * 4 = 32 rubles

Now that we know the price of the book is 32 rubles and the price of the notebook is 8 rubles, we can calculate the price difference:

Price difference = Price of the book - Price of the notebook

Substituting the values into the equation:

Price difference = 32 rubles - 8 rubles = 24 rubles

Therefore, the notebook is 24 rubles cheaper than the book.
