Answer 2

Calculation of the Cost of 7 Identical Notebooks

To calculate the cost of 7 identical notebooks, we need to determine the cost of a single notebook. According to the information provided, 9 identical notebooks cost 72 rubles

To find the cost of a single notebook, we can divide the total cost by the number of notebooks:

72 rubles / 9 notebooks = 8 rubles per notebook.

Therefore, each notebook costs 8 rubles.

To calculate the cost of 7 notebooks, we can multiply the cost of a single notebook by the number of notebooks:

8 rubles/notebook * 7 notebooks = 56 rubles.

Therefore, 7 identical notebooks cost 56 rubles.

Calculation of the Number of Notebooks that Can Be Purchased with 40 Rubles and 64 Rubles

To calculate the number of notebooks that can be purchased with 40 rubles, we need to divide the total amount by the cost of a single notebook.

40 rubles / 8 rubles/notebook = 5 notebooks.

Therefore, with 40 rubles, you can buy 5 notebooks.

To calculate the number of notebooks that can be purchased with 64 rubles:

64 rubles / 8 rubles/notebook = 8 notebooks.

Therefore, with 64 rubles, you can buy 8 notebooks.
