Answer 2

Problem Analysis

The student bought notebooks in two different styles: one with grid lines and one with ruled lines. The notebook with ruled lines cost 12 rubles more than the notebook with grid lines. We need to determine the price of the notebook with ruled lines.

Solution

Let's assume the price of the notebook with grid lines is x rubles. Since the notebook with ruled lines cost 12 rubles more, its price can be represented as x + 12 rubles.

According to the given information, the student bought both notebooks at the same price. Therefore, the total cost of the notebooks with grid lines and ruled lines should be the same.

The equation can be set up as follows:

x + (x + 12) = 2x + 12

Simplifying the equation:

2x + 12 = 2x + 12

The equation simplifies to 0 = 0, which means that the equation is true for any value of x.

Since the equation is true for any value of x, we cannot determine the exact price of the notebook with ruled lines based on the given information.

Therefore, the price of the notebook with ruled lines could be any value, as long as it is 12 rubles more than the price of the notebook with grid lines.
