Answer 2

Calculation of the Cost of 2 Pencils and 4 Notebooks

To calculate the cost of 2 pencils and 4 notebooks, we need to know the individual prices of the pencil and the notebook. According to the information provided, the pencil costs 1 tenge, and the notebook costs 10 tenge.

Let's calculate the total cost:

- 2 pencils: 2 * 1 tenge = 2 tenge - 4 notebooks: 4 * 10 tenge = 40 tenge

Therefore, the total cost of 2 pencils and 4 notebooks is 2 tenge + 40 tenge = 42 tenge.

Price Difference Between the Notebook and the Pencil

To determine the price difference between the notebook and the pencil, we need to compare their individual prices. According to the information provided, the pencil costs 1 tenge, and the notebook costs 10 tenge.

Let's calculate the price difference:

- Notebook price: 10 tenge - Pencil price: 1 tenge

The notebook is more expensive than the pencil by 10 tenge - 1 tenge = 9 tenge.

Therefore, the notebook is 9 tenge more expensive than the pencil.
