Calculation of the Cost of Chocolate Candies

To calculate the cost of 1 kg of chocolate candies, we need to consider the total cost of the candies and the total weight of the candies.

Given information: - 4 kg of caramel at 25 RUB per kg - 2 kg of chocolate candies - 1 kg of a mixture costs 30 RUB

Let's break down the calculation step by step:

1. Calculate the total cost of the caramel: - 4 kg of caramel at 25 RUB per kg - Total cost of caramel = 4 kg * 25 RUB/kg = 100 RUB 2. Calculate the total cost of the mixture: - 1 kg of the mixture costs 30 RUB - Total cost of the mixture = 1 kg * 30 RUB/kg = 30 RUB 3. Calculate the total cost of the candies: - Total cost of the candies = Total cost of the caramel + Total cost of the mixture - Total cost of the candies = 100 RUB + 30 RUB = 130 RUB

4. Calculate the total weight of the candies: - Total weight of the candies = Weight of caramel + Weight of chocolate candies - Total weight of the candies = 4 kg + 2 kg = 6 kg

5. Calculate the cost of 1 kg of chocolate candies: - Cost of 1 kg of chocolate candies = Total cost of the candies / Total weight of the candies - Cost of 1 kg of chocolate candies = 130 RUB / 6 kg = 21.67 RUB/kg (rounded to two decimal places)

Therefore, the cost of 1 kg of chocolate candies is approximately 21.67 RUB.

Please note that the calculation assumes that the cost per kg of caramel and the cost per kg of the mixture remain constant throughout the calculation.
