Answer 1

Can a situation like this happen? Why?

In the given scenario, the owl purchased a notebook for 4 rubles and a pen for 3 rubles, giving a total of 7 rubles. The owl then gave the shopkeeper 9 rubles and received 2 rubles in change. This situation is not possible because the owl paid more than the total cost of the items.

To understand why this situation is not possible, let's break it down step by step:

1. The owl purchased a notebook for 4 rubles and a pen for 3 rubles, which adds up to a total of 7 rubles. 2. The owl gave the shopkeeper 9 rubles, which is more than the total cost of the items. 3. The shopkeeper gave the owl 2 rubles in change.

If we add the amount the owl paid (9 rubles) to the change received (2 rubles), we get a total of 11 rubles. However, the total cost of the items purchased was only 7 rubles. This means that the owl paid more than necessary and received more change than expected.

Therefore, it is not possible for the owl to have paid 9 rubles for items that cost a total of 7 rubles and received 2 rubles in change. This situation violates the principle of conservation of money, where the total amount paid should be equal to the total cost of the items plus any change received.

In conclusion, the situation described in the question is not possible because the owl paid more than the total cost of the items and received more change than expected.
