Problem Analysis

We are given the information that a book, an album, and a notebook were purchased. The total cost of the purchase, excluding the notebook, was 75 rubles. The book costs 40 rubles. We need to determine the cost of the album and whether we have enough information to find the price of the notebook.

Solution

Let's assume the cost of the album is x rubles.

The total cost of the purchase, including the book, album, and notebook, is the sum of their individual costs:

40 (book) + x (album) + ? (notebook) = total cost

We also know that the total cost, excluding the notebook, is 75 rubles:

40 (book) + x (album) = 75

To find the cost of the album, we can subtract the cost of the book from the total cost:

x (album) = 75 - 40 = 35 rubles

Therefore, the album costs 35 rubles.

To determine if we have enough information to find the price of the notebook, we need another equation. Unfortunately, we don't have any additional information about the notebook's price. Therefore, we do not have enough information to find the price of the notebook.

Answer

The album costs 35 rubles. We do not have enough information to find the price of the notebook.
