Problem:

Для школьного буфета купили 18 пачек индийского чая и 20 пачек краснодарского. Израсходовали 8 пачек. Сколько пачек осталось?

Solution 1:

To find the number of tea packets left, we can subtract the number of packets used from the total number of packets purchased.

Let's calculate it step by step:

1. Total number of packets purchased: 18 (Indian tea) + 20 (Krasnodar tea) = 38 packets. 2. Number of packets used: 8 packets. 3. Number of packets left: 38 packets - 8 packets = 30 packets.

Therefore, there are 30 packets of tea left.

Solution 2:

Another way to solve this problem is by using the concept of addition and subtraction.

1. Total number of packets purchased: 18 (Indian tea) + 20 (Krasnodar tea) = 38 packets. 2. Number of packets used: 8 packets. 3. Number of packets left: 38 packets - 8 packets = 30 packets.

So, there are 30 packets of tea left.

Solution 3:

We can also solve this problem by using the information provided in the search results.

According to the search results, the total number of packets purchased is 38. The number of packets used is 8. To find the number of packets left, we can subtract the number of packets used from the total number of packets purchased.

Number of packets left = Total number of packets purchased - Number of packets used = 38 - 8 = 30 packets.

Therefore, there are 30 packets of tea left.

Note: The search results did not provide a direct answer to the question, but we can still use the information provided to solve the problem.
