Problem Analysis

We are given that two identical packs of ice cream and a packet of juice cost a total of 38 rubles. We also know that the pack of ice cream is 11 rubles cheaper than the packet of juice. We need to find the cost of the packet of juice.

Solution

Let's assume the cost of the packet of juice is x rubles.

According to the given information, the cost of two identical packs of ice cream is 38 - x rubles.

Since the pack of ice cream is 11 rubles cheaper than the packet of juice, we can write the following equation:

38 - x = x + 11

Simplifying the equation:

38 - 11 = x + x

27 = 2x

Dividing both sides by 2:

x = 27 / 2

Therefore, the cost of the packet of juice is 13.5 rubles.

Answer

The packet of juice costs 13.5 rubles.

Explanation

Let's go through the solution step by step:

1. We assume the cost of the packet of juice is x rubles. 2. The cost of two identical packs of ice cream is 38 - x rubles. 3. Since the pack of ice cream is 11 rubles cheaper than the packet of juice, we set up the equation 38 - x = x + 11. 4. Simplifying the equation, we get 27 = 2x. 5. Dividing both sides by 2, we find that x = 27 / 2. 6. Therefore, the cost of the packet of juice is 13.5 rubles.
