Answer 3

Task Solution:

Let's solve the problem step by step.

Step 1: Define the Variables Let's assume the cost of the notebook in a grid is x rubles.

Step 2: Formulate the Equations According to the given information, the student bought 4 more notebooks in a line than in a grid, and the total cost was 12 rubles more. This can be represented by the following equation: \[ (x+4)(x) + 12 = x^2 + 4x + 12 \]

Step 3: Solve the Equation We can solve the equation to find the value of x.

\[ x^2 + 4x + 12 = x^2 + 4x + 12 \]

The equation simplifies to: \[ 0 = 0 \]

This means that the equation is an identity, and there are infinitely many solutions. This suggests that there might be a mistake in the problem statement or the provided information.

Unfortunately, based on the provided information, it's not possible to determine the exact price of the notebook in the grid. If there are additional details or corrections to the problem, please provide them for further assistance.
