Calculation of the Price of Cookies

To find the price of the cookies, we can set up a system of equations based on the given information.

Let's assume the price of the cookies is x rubles per kilogram.

According to the given information: - The price of 8 kg of candy is 82.5 rubles per kilogram. - The price of 12 kg of cookies is 930 rubles.

Using this information, we can set up the following equations:

Equation 1: 8 * 82.5 = total cost of candy Equation 2: 12 * x = total cost of cookies

Simplifying Equation 1: 8 * 82.5 = 660 rubles

Simplifying Equation 2: 12 * x = 930 rubles

To find the value of x, we can divide both sides of Equation 2 by 12: x = 930 / 12

Now, let's calculate the value of x:

x = 930 / 12 = 77.5 rubles per kilogram

Therefore, the price of the cookies is 77.5 rubles per kilogram.
