Calculation of the Price of 1 kg of Sausage

To calculate the price of 1 kg of sausage, we need to use the given information:

- The total cost of 400 g of cheese and 1.2 kg of sausage is 126 rubles and 80 kopeks. - The price of 1 kg of cheese is 95 rubles.

Let's break down the calculation step by step:

1. Calculate the cost of 400 g of cheese: - The price of 1 kg of cheese is 95 rubles. - Therefore, the price of 400 g of cheese is (400/1000) * 95 = 38 rubles.

2. Calculate the cost of 1.2 kg of sausage: - The total cost of 400 g of cheese and 1.2 kg of sausage is 126 rubles and 80 kopeks. - Subtract the cost of 400 g of cheese from the total cost to find the cost of 1.2 kg of sausage: - Total cost - Cost of cheese = Cost of sausage - 126 rubles and 80 kopeks - 38 rubles = 88 rubles and 80 kopeks.

3. Calculate the price of 1 kg of sausage: - The cost of 1.2 kg of sausage is 88 rubles and 80 kopeks. - Therefore, the price of 1 kg of sausage is (88.80 / 1.2) = 74 rubles.

Therefore, the price of 1 kg of sausage is 74 rubles.
