Calculation of the Potato Price

To calculate the price of potatoes, we need to determine the cost per kilogram (kg) of potatoes. We know that the total cost of the potatoes is 420 rubles and the quantity of potatoes purchased is 5 kg.

To find the cost per kilogram, we can divide the total cost by the quantity of potatoes:

Cost per kilogram of potatoes = Total cost / Quantity of potatoes

Substituting the given values:

Cost per kilogram of potatoes = 420 rubles / 5 kg

Performing the calculation:

Cost per kilogram of potatoes = 84 rubles/kg

Therefore, the price of potatoes is 84 rubles per kilogram.
