Problem Analysis

The problem states that a student bought three times as many grid notebooks as line notebooks, and the number of grid notebooks was 18 more than the number of line notebooks. We need to find the total number of notebooks the student bought.

Solution

Let's assume the number of line notebooks the student bought is x. According to the problem, the student bought three times as many grid notebooks as line notebooks, so the number of grid notebooks is 3x. Additionally, the problem states that the number of grid notebooks is 18 more than the number of line notebooks, so we can set up the equation:

3x = x + 18

To solve this equation, we can subtract x from both sides:

2x = 18

Then, we divide both sides by 2:

x = 9

Therefore, the student bought 9 line notebooks. To find the total number of notebooks, we can substitute this value back into the equation:

Total number of notebooks = x + 3x = 9 + 3(9) = 9 + 27 = 36

So, the student bought a total of 36 notebooks.

Answer

The student bought a total of 36 notebooks.
