Answer 3

Calculating the Cost of Notebooks

To find the cost of 11 notebooks, given that 2 notebooks cost the same as 3 notepads, and one notepad costs 9 rubles, we can calculate as follows:

1. Cost of 2 notebooks: - The cost of 2 notebooks is the same as the cost of 3 notepads. - Therefore, the cost of 2 notebooks is 3 * 9 = 27 rubles. 2. Cost of 1 notebook: - To find the cost of 1 notebook, we divide the cost of 2 notebooks by 2. - Therefore, the cost of 1 notebook is 27 / 2 = 13.5 rubles.

3. Cost of 11 notebooks: - Finally, to find the cost of 11 notebooks, we multiply the cost of 1 notebook by 11. - Therefore, the cost of 11 notebooks is 13.5 * 11 = 148.5 rubles.

So, 11 notebooks cost 148.5 rubles.
