Problem Analysis

We are given the information that 2 packages of milk and 1 package of cottage cheese were purchased for a total of 75 rubles. Additionally, we are told that the price of the cottage cheese package is 6 rubles more expensive than the milk package. We need to determine the price of the milk package.

Solution

Let's assume the price of the milk package is x rubles. Since the cottage cheese package is 6 rubles more expensive, its price would be x + 6 rubles.

According to the given information, the total cost of 2 milk packages and 1 cottage cheese package is 75 rubles. We can express this as an equation:

2x + (x + 6) = 75

Simplifying the equation, we get:

3x + 6 = 75

Subtracting 6 from both sides of the equation:

3x = 69

Dividing both sides of the equation by 3:

x = 23

Therefore, the price of the milk package is 23 rubles.

Answer

The price of the milk package is 23 rubles.
