Answer 1

Calculation of the Total Cost

To calculate the total cost, we need to determine the price of one thin notebook and the price of one regular notebook.

Let's assume that the price of one regular notebook is x rubles. According to the given information, the price of one thin notebook is 5 times less than the price of a regular notebook. Therefore, the price of one thin notebook is x/5 rubles.

Now, we can calculate the total cost of one regular notebook and 10 thin notebooks.

The total cost of one regular notebook is x rubles.

The total cost of 10 thin notebooks is 10 * (x/5) = 2x rubles.

To find the value of x, we can use the information given in the search results.

According to source the total cost of one regular notebook is 120 rubles.

Therefore, the total cost of one regular notebook and 10 thin notebooks is 120 + 2x rubles.

Let's calculate the total cost:

120 + 2x = 120 + 2 * 120 = 120 + 240 = 360 rubles

So, the total cost of one regular notebook and 10 thin notebooks is 360 rubles.
