Answer 1

2*5=10 рублей
5*1=5 рублей
10+5=15 руб

Answer 2

Number of Two-Ruble Coins and Sounds in the Word "Старт"

If we assume that I have as many two-ruble coins as there are sounds in the word "Старт," we can determine the number of coins by counting the sounds in the word. The word "Старт" consists of five sounds: "с," "т," "а," "р," and "т" [[1]]. Therefore, I would have five two-ruble coins.

Number of Five-Ruble Coins and Syllables in the Word "Старт"

Similarly, if we assume that I have as many five-ruble coins as there are syllables in the word "Старт," we can determine the number of coins by counting the syllables in the word. The word "Старт" has one syllable [[2]]. Therefore, I would have one five-ruble coin.

Possible Purchases without Change

Now, let's consider the purchases I can make without receiving any change. The available options are as follows:

1. An item priced at 12 rubles. 2. A notebook priced at 17 rubles. 3. A pencil priced at 8 rubles. 4. A postage stamp priced at 11 rubles.

To determine which purchases I can make, we need to find the combination of items that adds up to the total amount I have, which is 12 rubles.

By adding the prices of the items, we find that the total cost of the first three items (12 + 17 + 8) is 37 rubles, which exceeds the amount I have. Therefore, I cannot purchase the first three items together.

However, if I consider the fourth item alone, which costs 11 rubles, I can afford it with the amount I have. Therefore, I can purchase the postage stamp priced at 11 rubles without receiving any change.

In summary, I can purchase the postage stamp priced at 11 rubles without receiving any change, but I cannot afford the other items listed.

I hope this helps! Let me know if you have any further questions.
