Calculation of the Price of Beef on the Market

To calculate the price a buyer would pay for 3 kg of beef on the market, we need to consider that the price of beef on the market is 20% lower than the price in the supermarket. The price of beef in the supermarket is 320 rubles per 1 kg.

To find the price of beef on the market, we need to calculate 20% of 320 rubles and subtract it from the supermarket price.

Step 1: Calculate 20% of 320 rubles: 20% of 320 rubles = (20/100) * 320 rubles = 64 rubles

Step 2: Subtract 20% of 320 rubles from 320 rubles to find the price of beef on the market: 320 rubles - 64 rubles = 256 rubles

Therefore, the price of beef on the market is 256 rubles per 1 kg.

Calculation of the Total Price for 3 kg of Beef on the Market

To calculate the total price for 3 kg of beef on the market, we need to multiply the price per 1 kg by the weight of the beef.

Step 1: Multiply the price per 1 kg (256 rubles) by the weight of the beef (3 kg): 256 rubles/kg * 3 kg = 768 rubles

Therefore, the buyer would pay 768 rubles for 3 kg of beef on the market.
