Answer 3

Problem Analysis

We are given that one girl bought 4 notebooks and another girl bought 6 notebooks of the same kind. The total cost of the notebooks bought by the second girl is 48 rubles more than the total cost of the notebooks bought by the first girl. We need to find out how much each girl paid for the notebooks.

Solution

Let's assume the cost of each notebook is x rubles.

The first girl bought 4 notebooks, so the total cost for her is 4x rubles.

The second girl bought 6 notebooks, so the total cost for her is 6x rubles.

According to the problem, the total cost for the second girl is 48 rubles more than the total cost for the first girl. Mathematically, we can represent this as:

6x = 4x + 48

To find the value of x, we can solve this equation.

Solving the Equation

Subtracting 4x from both sides of the equation, we get:

6x - 4x = 48

Simplifying the equation, we have:

2x = 48

Dividing both sides of the equation by 2, we get:

x = 24

Answer

Each girl paid 24 rubles for the notebooks.

Verification

To verify our answer, we can substitute the value of x back into the equation and check if it holds true.

For the first girl, who bought 4 notebooks, the total cost would be:

4 * 24 = 96 rubles

For the second girl, who bought 6 notebooks, the total cost would be:

6 * 24 = 144 rubles

The total cost for the second girl is indeed 48 rubles more than the total cost for the first girl, which confirms our answer.

Therefore, each girl paid 24 rubles for the notebooks.
