Answer 2

Calculation of the Total Cost

To calculate the total cost of the carrots and onions, we need to multiply the price per kilogram by the number of kilograms purchased for each vegetable.

Given: - Carrots cost 28 rubles per kilogram. - Onions are twice as cheap as carrots.

Let's calculate the cost of the vegetables:

1. Carrots: - Price per kilogram: 28 rubles - Quantity purchased: 2 kilograms - Cost of carrots: 28 rubles/kg * 2 kg = 56 rubles

2. Onions: - Price per kilogram: Half the price of carrots = 28 rubles / 2 = 14 rubles - Quantity purchased: 3 kilograms - Cost of onions: 14 rubles/kg * 3 kg = 42 rubles

To find the total cost, we add the cost of carrots and onions:

Total cost = Cost of carrots + Cost of onions = 56 rubles + 42 rubles = 98 rubles

Therefore, the total amount of money paid for the vegetables is 98 rubles.
