Solving the Problem

To solve the problem, we can use the information provided in the question. Let's denote the cost of one notebook as x.

Kolya bought 9 notebooks, so the cost for him is 9x. Vasya bought 5 notebooks, so the cost for him is 5x.

Given that the total cost for both of them is 98 rubles, we can set up the equation: 9x + 5x = 98

Solving for x will give us the cost of one notebook.

Calculation

9x + 5x = 98 14x = 98 x = 98 / 14 x = 7

Answer

So, the cost of one notebook is 7 rubles.
