Calculation of the Cost of International Phone Calls

To calculate the cost of the director's international phone calls, we need to consider the rates for each country. According to the given information, the cost of a 1-minute call to Belarus is 1 ruble, to China is 5 rubles, and to France is 3 kopeks (0.03 rubles). The duration of each call is 5 minutes.

Let's calculate the total cost for each country:

- Belarus: 6 calls * 5 minutes * 1 ruble per minute = 30 rubles. - France: 4 calls * 5 minutes * 0.03 rubles per minute = 0.6 rubles. - China: 2 calls * 5 minutes * 5 rubles per minute = 50 rubles.

Now, let's calculate the total cost of all the international phone calls:

Total cost = Cost to Belarus + Cost to France + Cost to China = 30 rubles + 0.6 rubles + 50 rubles = 80.6 rubles.

Therefore, the total cost of the director's international phone calls is 80.6 rubles.

Please note that the given information does not provide any specific currency for the cost of the calls. However, since the amounts are mentioned in rubles, we assume that the currency is rubles.
