Answer 2

Calculation of the Total Cost

To calculate the total cost, we need to consider the price per notebook, the number of notebooks purchased, and the discount applied for purchasing more than 50 notebooks.

Given that each notebook costs 14 rubles and the discount is 5% off the total purchase price, we can calculate the total cost as follows:

1. Calculate the cost of 70 notebooks without the discount: - Price per notebook: 14 rubles - Number of notebooks: 70 - Total cost without discount: 14 rubles/notebook * 70 notebooks = 980 rubles.

2. Calculate the discount amount: - Total cost without discount: 980 rubles - Discount rate: 5% - Discount amount: 5% * 980 rubles = 49 rubles.

3. Calculate the total cost with the discount: - Total cost without discount: 980 rubles - Discount amount: 49 rubles - Total cost with discount: 980 rubles - 49 rubles = 931 rubles.

Therefore, the customer will pay 931 rubles for 70 notebooks with a 5% discount applied.
