Пошаговое объяснение:

За 6 обложек по 4 тенге заплатили 6*4 = 24 тенге.

Тетради стоят 8 тенге каждая.

24:8 = 3 тетради купили на эти деньги.

Answer 2

Solution:

To solve this problem, we can use a system of equations. Let's denote the number of notebooks as x and the number of covers as y.

Given: 1. The cost of 6 covers at 4 tenges each is equal to the cost of several notebooks at 8 tenges each. 2. The total cost of covers is equal to the total cost of notebooks.

We can express this information in the following equations:

1. 6y = 8x 2. 4y = 8x

Calculations:

We can solve this system of equations to find the values of x and y.

From equation 1, we can express y in terms of x: y = (8/6)x

Substitute this value of y into equation 2: 4(8/6)x = 8x (32/6)x = 8x x = (6/32) * 8 x = 12

So, the number of notebooks bought is 12.

Conclusion:

Therefore, the person bought 12 notebooks.
