Answer 3

Calculating the Cost of the Pen

To calculate the cost of the pen, we can use the information provided. We know that the total cost of the pen, album, and notebooks is 54 rubles, and the cost of the pen is 1/9 of the total spent.

Using this information, we can calculate the cost of the pen as follows:

Cost of the pen = Total spent * (1/9)

Substituting the given total spent of 54 rubles:

Cost of the pen = 54 * (1/9) Cost of the pen = 6 rubles

So, Yura paid 6 rubles for the pen.

Calculating the Cost of the Album

Similarly, to calculate the cost of the album, we can use the information provided. We know that the total cost of the pen, album, and notebooks is 54 rubles, and the cost of the album is 5/9 of the total spent.

Using this information, we can calculate the cost of the album as follows:

Cost of the album = Total spent * (5/9)

Substituting the given total spent of 54 rubles:

Cost of the album = 54 * (5/9) Cost of the album = 30 rubles

So, Yura paid 30 rubles for the album.
