Answer 2

Calculation of the Average Price of the Three Types of Candy

To calculate the average price of the three types of candy, we need to determine the total cost of each type of candy and then divide it by the total weight of the candy.

Let's break down the information provided:

- Petya bought 2 kilograms of one type of candy at 64 rubles per kilogram. - Petya bought 4 kilograms of two types of candy at 82 rubles per kilogram. - Petya bought three kilograms of three types of candy, and the average price of all three types was 88 rubles per kilogram.

To find the cost of each type of candy, we can use the following equations:

- Cost of the first type of candy: 2 kilograms * 64 rubles per kilogram = 128 rubles - Cost of the second type of candy: 4 kilograms * 82 rubles per kilogram = 328 rubles - Cost of the third type of candy: 3 kilograms * 88 rubles per kilogram = 264 rubles

Now, let's calculate the total cost of all the candy:

- Total cost of all candy: 128 rubles + 328 rubles + 264 rubles = 720 rubles

To find the average price of the three types of candy, we divide the total cost by the total weight:

- Average price of the three types of candy: 720 rubles / 9 kilograms = 80 rubles per kilogram

Therefore, the cost of one kilogram of candy of each of the three types is 80 rubles.
