Calculation of Sasha's Payment

To calculate how much Sasha will pay for 9 pencils and 8 notebooks, we can use the given information about the payments made by Egor and Katya.

According to the information provided, Egor paid 126 rubles for 5 pencils and 4 notebooks, while Katya paid 84 rubles for 2 notebooks and 2 pencils.

Let's break down the problem step by step:

1. Calculate the cost of one pencil: - Egor paid 126 rubles for 5 pencils, so the cost of one pencil is 126 rubles divided by 5 pencils, which is 25.2 rubles per pencil.

2. Calculate the cost of one notebook: - Egor paid 126 rubles for 4 notebooks, so the cost of one notebook is 126 rubles divided by 4 notebooks, which is 31.5 rubles per notebook.

3. Calculate the total cost of 9 pencils: - The cost of one pencil is 25.2 rubles, so the total cost of 9 pencils is 25.2 rubles multiplied by 9 pencils, which is 226.8 rubles.

4. Calculate the total cost of 8 notebooks: - The cost of one notebook is 31.5 rubles, so the total cost of 8 notebooks is 31.5 rubles multiplied by 8 notebooks, which is 252 rubles.

5. Calculate Sasha's total payment: - Sasha will pay for 9 pencils and 8 notebooks, so the total payment is the sum of the costs of the pencils and notebooks, which is 226.8 rubles plus 252 rubles, equaling 478.8 rubles.

Therefore, Sasha will pay 478.8 rubles for 9 pencils and 8 notebooks.
