Answer 2

Minimum number of ice cream packs Sergey can buy

To determine the minimum number of ice cream packs Sergey can buy, we need to consider the denominations of his coins and the price of each ice cream pack.

Given that Sergey only has 5-ruble coins and the price of each ice cream pack is 39 rubles, we need to find the smallest multiple of 39 that can be paid using only 5-ruble coins.

To find this, we can divide 39 by 5 and round up to the nearest whole number. This will give us the minimum number of ice cream packs Sergey can buy.

Let's calculate it:

39 / 5 = 7.8

Rounding up to the nearest whole number, Sergey can buy a minimum of 8 ice cream packs.

Therefore, Sergey can buy at least 8 packs of ice cream using his 5-ruble coins.

Please note that this calculation assumes that Sergey can use any number of 5-ruble coins to make the payment, without any restrictions on the number of coins he can use.
