Answer 2

Calculation of Vanya's Purchase Cost

To calculate the cost of Vanya's purchase, we need to determine the price of each ornament. According to the information provided, Olya bought 10 ornaments for 200 lei. Therefore, we can calculate the price per ornament by dividing the total cost by the number of ornaments:

Price per ornament = Total cost / Number of ornaments

In this case, the total cost is 200 lei, and the number of ornaments is 10. Plugging these values into the formula, we get:

Price per ornament = 200 lei / 10 ornaments = 20 lei

So, each ornament costs 20 lei.

Now, we can calculate the cost of Vanya's purchase. It is mentioned that Vanya bought 5 ornaments. Since the price per ornament is 20 lei, we can multiply the number of ornaments by the price per ornament:

Vanya's purchase cost = Number of ornaments * Price per ornament

Plugging in the values, we get:

Vanya's purchase cost = 5 ornaments * 20 lei/ornament = 100 lei

Therefore, the cost of Vanya's purchase is 100 lei.

Please note that the information provided is based on the given scenario and calculations.
