Answer 2

To find out how much was paid for the notebooks, we need to determine the cost of the notebooks relative to the cost of the book and album.

Let's assume the cost of the notebooks is represented by x.

According to the given information, the cost of the notebooks is 0.3 tenths (or 3/10) of the cost of the book and album.

We also know that the book and album together cost 180 rubles, and the book alone is 50 rubles more expensive than the notebooks.

To calculate the cost of the notebooks, we can set up the following equation:

x = 0.3 * (180 - x - 50)

Let's solve this equation to find the value of x.
