0,9·x = 25,62 - 14,28

0,9·x = 11,34

x = 11,34/0,9

x = 12,6

Calculation of the Cost of 1 kg of Sausage

To calculate the cost of 1 kg of sausage, we need to use the given information about the cost of 2.1 kg of minced meat and 0.9 kg of sausage, as well as the total cost of 25.62 rubles.

Let's break down the problem step by step:

1. Calculate the cost of 1 kg of minced meat: - Given: 2.1 kg of minced meat costs 25.62 rubles. - To find the cost of 1 kg, we divide the total cost by the weight: 25.62 rubles / 2.1 kg = 12.2 rubles per kg of minced meat. (Source

2. Calculate the cost of 1 kg of sausage: - Given: 1 kg of minced meat costs 6.8 rubles. - We can use the cost of 1 kg of minced meat to find the cost of 0.9 kg of sausage. - Multiply the cost of 1 kg of minced meat by 0.9 to find the cost of 0.9 kg of sausage: 6.8 rubles/kg * 0.9 kg = 6.12 rubles. - Subtract the cost of 0.9 kg of sausage from the total cost to find the cost of 0.1 kg of sausage: 25.62 rubles - 6.12 rubles = 19.5 rubles. - Divide the cost of 0.1 kg of sausage by 0.1 kg to find the cost of 1 kg of sausage: 19.5 rubles / 0.1 kg = 195 rubles per kg of sausage.

Therefore, the cost of 1 kg of sausage is 195 rubles.
