Calculation of the Difference in the Number of Notebooks Purchased by Olga and Petya

To calculate the difference in the number of notebooks purchased by Olga and Petya, we need to determine the cost of each notebook and the difference in the total amount paid by Olga and Petya.

Given: - The price of each notebook is 12 rubles. - Olga paid 24 rubles more than Petya for her notebooks.

Let's calculate the number of notebooks purchased by each person:

1. Determine the cost of Petya's notebooks: - Let's assume Petya bought 'x' notebooks. - The total cost of Petya's notebooks is 12 rubles per notebook multiplied by 'x' notebooks, which is 12x rubles.

2. Determine the cost of Olga's notebooks: - Olga paid 24 rubles more than Petya, so the total cost of Olga's notebooks is 12x + 24 rubles.

Now, let's find the difference in the number of notebooks purchased by Olga and Petya:

3. Calculate the difference in the total amount paid by Olga and Petya: - The difference in the total amount paid by Olga and Petya is 12x + 24 rubles - 12x rubles, which simplifies to 24 rubles.

Since the price of each notebook is 12 rubles, the difference in the number of notebooks purchased by Olga and Petya can be calculated by dividing the difference in the total amount paid by the price of each notebook:

4. Calculate the difference in the number of notebooks purchased: - The difference in the number of notebooks purchased by Olga and Petya is 24 rubles divided by 12 rubles per notebook, which simplifies to 2 notebooks.

Therefore, Olga bought 2 notebooks more than Petya.
