Problem Analysis

To find the price of a pack of cottage cheese and a pack of milk, given that the pack of cottage cheese is 6 rubles more expensive than the pack of milk, and the total cost of both items is 90 rubles.

Solution

Let's assume the price of the pack of milk is x rubles. According to the given information, the price of the pack of cottage cheese is 6 rubles more than the pack of milk. Therefore, the price of the pack of cottage cheese is x + 6 rubles.

The total cost of both items is 90 rubles. So, we can write the equation:

x + (x + 6) = 90

Simplifying the equation:

2x + 6 = 90

Subtracting 6 from both sides:

2x = 84

Dividing both sides by 2:

x = 42

Therefore, the price of the pack of milk is 42 rubles.

To find the price of the pack of cottage cheese, we substitute the value of x into the equation:

x + 6 = 42 + 6 = 48

Therefore, the price of the pack of cottage cheese is 48 rubles.

Answer

The price of the pack of cottage cheese is 48 rubles and the price of the pack of milk is 42 rubles.
