Problem Analysis

To solve this problem, we need to find the cost of a packet of milk given that the price of a packet of cottage cheese is 14 rubles and 50 kopeks, and the number of packets of milk and cottage cheese is the same. Additionally, we know that the price of the cottage cheese is 30 rubles more than the price of the milk.

Solution

Let's assume the cost of a packet of milk is x rubles. Since the price of the cottage cheese is 30 rubles more than the price of the milk, the cost of a packet of cottage cheese is (x + 30) rubles.

We are given that the price of a packet of cottage cheese is 14 rubles and 50 kopeks. To convert the kopeks to rubles, we divide by 100. Therefore, the price of a packet of cottage cheese is 14.50 rubles.

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

x + 30 = 14.50

Now, let's solve the equation to find the value of x.

Calculation

x + 30 = 14.50

Subtracting 30 from both sides:

x = 14.50 - 30

x = -15.50

Since the cost of a packet of milk cannot be negative, we can conclude that there is an error in the given information or calculation. Please double-check the values provided.
