Question

билет в музей стоит 250 рублей. Стоимость билета для школьника составляет 30% от полной стоимости билета. Сколько рублей нужно заплатить за билеты на группу, состоящую из 25 школьников и 2 учителей.

Answer 1

1) 250:100*30=75 руб - стоит билет для школьника

2) 25*75=1875 руб - цена билетов для школьников

3) 2*250=500 руб - цена билетов для учителей

4) 1875+500=2375 руб - цена всех билетов

Answer 2

250:100*30=75 рублей стоит билет для школьника

25*75=1875 руб будет стоить 25 билетов для школьников

250*2=500 руб стоят билеты для учителей

1875+500=2375 руб стоят все билеты

Answer 3

Calculation of the Total Cost of Tickets

To calculate the total cost of tickets for a group consisting of 25 schoolchildren and 2 teachers, we need to determine the cost of each ticket and then multiply it by the number of people in the group.

The cost of a ticket for a schoolchild is 30% of the full ticket price. Given that the full ticket price is 250 rubles, we can calculate the cost of a schoolchild's ticket as follows:

Cost of schoolchild's ticket = 30% of 250 rubles = 0.3 * 250 rubles = 75 rubles.

The cost of a teacher's ticket is not specified in the question, so we will assume it is the same as the full ticket price of 250 rubles.

Now, let's calculate the total cost of tickets for the group:

Number of schoolchildren = 25 Number of teachers = 2

Total cost of schoolchildren's tickets = Cost of schoolchild's ticket * Number of schoolchildren = 75 rubles * 25 = 1875 rubles

Total cost of teachers' tickets = Cost of full ticket * Number of teachers = 250 rubles * 2 = 500 rubles

Total cost of tickets for the group = Total cost of schoolchildren's tickets + Total cost of teachers' tickets = 1875 rubles + 500 rubles = 2375 rubles

Therefore, the group consisting of 25 schoolchildren and 2 teachers would need to pay 2375 rubles for the tickets to the museum.

Please note that the sources provided do not directly mention the specific ticket prices for schoolchildren or teachers in this context. However, the calculations are based on the given information and general knowledge of percentage calculations.
