Calculation of Phone Call Costs

To calculate the cost of each phone call, we need to consider the tariff (price) and duration of each call, as provided in the table:

| Number | Tariff (Price) | Duration (seconds) | |--------|----------------|--------------------| | 1 | 3 rubles | 300 | | 2 | 4 rubles | 240 | | 3 | 2 rubles 50 kopeks | 600 |

Let's calculate the cost of each call:

1. Call from Number 1: - Tariff: 3 rubles per minute - Duration: 300 seconds (5 minutes) - Cost: 3 rubles/minute x 5 minutes = 15 rubles.

2. Call from Number 2: - Tariff: 4 rubles per minute - Duration: 240 seconds (4 minutes) - Cost: 4 rubles/minute x 4 minutes = 16 rubles.

3. Call from Number 3: - Tariff: 2 rubles 50 kopeks per minute - Duration: 600 seconds (10 minutes) - Cost: 2 rubles 50 kopeks/minute x 10 minutes = 25 rubles.

Therefore, the cost of each phone call is as follows: - Call from Number 1: 15 rubles - Call from Number 2: 16 rubles - Call from Number 3: 25 rubles.

Please note that the cost of the calls from Number 1 and Number 2 is based on the assumption that the duration provided is in seconds, as mentioned in the table. If the duration is already in minutes, please let me know so that I can recalculate the costs accordingly.
