Answer 1

Calculation of the Cost of the Pen

To calculate the cost of the pen, we need to determine the total amount of money spent by Yuri and the fraction of that amount that corresponds to the cost of the pen.

According to the information provided, Yuri bought a pen, an album, and a notebook, and paid a total of 54 rubles for the purchase. The cost of the pen is stated to be 1/9 of the total amount spent.

Let's denote the cost of the pen as "x" rubles. We can set up the following equation to represent the given information:

x + cost of the album + cost of the notebook = 54 rubles

Since the cost of the pen is stated to be 1/9 of the total amount spent, we can express it as:

x = (1/9) * (total amount spent)

Now, we can substitute this expression for "x" in the equation above:

(1/9) * (total amount spent) + cost of the album + cost of the notebook = 54 rubles

However, we don't have information about the cost of the album or the notebook, so we cannot determine their exact values. Therefore, it is not possible to calculate the precise cost of the pen based on the given information.

Please provide additional information if available, or let me know if there is anything else I can assist you with.
