Problem Statement

In a kiosk, school notebooks are sold at a price of a ruble per notebook, while general notebooks are sold at a price of c rubles per notebook. The task is to determine the total cost of 5 school notebooks and solve the problem using two different methods.

Solution

To find the total cost of 5 school notebooks, we need to multiply the price of a school notebook by the number of notebooks. Since we have 5 school notebooks, the total cost can be calculated as follows:

Method 1: Multiplication The total cost of 5 school notebooks can be calculated by multiplying the price of a school notebook by the number of notebooks: Total cost = Price per school notebook * Number of school notebooks

In this case, the price per school notebook is a ruble, and the number of school notebooks is 5. Therefore, the total cost can be calculated as: Total cost = 1 ruble * 5 school notebooks = 5 rubles.

Method 2: Addition Alternatively, we can calculate the total cost by adding the price of each school notebook together: Total cost = Price of first school notebook + Price of second school notebook + Price of third school notebook + Price of fourth school notebook + Price of fifth school notebook

Since the price of each school notebook is 1 ruble, the total cost can be calculated as: Total cost = 1 ruble + 1 ruble + 1 ruble + 1 ruble + 1 ruble = 5 rubles.

Therefore, both methods yield the same result, and the total cost of 5 school notebooks is 5 rubles.
