Problem Analysis

To find the price of the mixed assortment of candies, we need to calculate the average price per kilogram. We are given the prices of four types of candies: 72 rubles/kg, 75 rubles/kg, 80 rubles/kg, and 85 rubles/kg.

Solution

To find the average price per kilogram, we need to calculate the total price of the candies and divide it by the total weight.

Let's calculate the total price: - The price of the first type of candy is 72 rubles/kg. - The price of the second type of candy is 75 rubles/kg. - The price of the third type of candy is 80 rubles/kg. - The price of the fourth type of candy is 85 rubles/kg.

To find the total price, we need to multiply the price of each type of candy by its weight. Since each type of candy weighs 1 kg, the total price is the sum of the prices of all four types of candies.

The total price can be calculated as follows: Total Price = (Price of the first type of candy * Weight of the first type of candy) + (Price of the second type of candy * Weight of the second type of candy) + (Price of the third type of candy * Weight of the third type of candy) + (Price of the fourth type of candy * Weight of the fourth type of candy)

Since each type of candy weighs 1 kg, the equation simplifies to: Total Price = Price of the first type of candy + Price of the second type of candy + Price of the third type of candy + Price of the fourth type of candy

Now, let's substitute the given prices into the equation and calculate the total price.

Calculation

Total Price = 72 rubles/kg + 75 rubles/kg + 80 rubles/kg + 85 rubles/kg

Total Price = 312 rubles

Answer

The total price of the mixed assortment of candies is 312 rubles/kg.
