Problem Analysis

To solve this problem, we need to determine the cost of 4 identical packages of milk, given that the cost of 8 identical packages is 45 rubles more than the cost of 5 identical packages.

Solution

Let's assume the cost of 5 identical packages of milk is x rubles. According to the given information, the cost of 8 identical packages is 45 rubles more than the cost of 5 identical packages.

So, the cost of 8 identical packages is x + 45 rubles.

To find the cost of 1 identical package, we can divide the cost of 8 identical packages by 8: 1 identical package = (x + 45) / 8 rubles.

Now, we need to find the cost of 4 identical packages. We can multiply the cost of 1 identical package by 4: 4 identical packages = 4 * [(x + 45) / 8] rubles.

Let's calculate the cost of 4 identical packages using this formula.

Calculation

The cost of 4 identical packages of milk is 4 * [(x + 45) / 8] rubles.

Answer

The cost of 4 identical packages of milk is 4 * [(x + 45) / 8] rubles.

Please note that we don't have the exact value of x from the given information, so we cannot provide the exact cost. However, you can substitute the value of x with any number to calculate the cost of 4 identical packages.
