Calculation of the Total Cost of Tickets for the Group

To calculate the total cost of tickets for the group, we need to determine the cost of tickets for both adults and schoolchildren and then multiply those costs by the respective number of adults and schoolchildren in the group.

Given: - The cost of an adult ticket is 2800 rubles. - The cost of a schoolchild ticket is 15% of the cost of an adult ticket.

Let's calculate the cost of tickets for the group step by step:

1. Calculate the cost of a schoolchild ticket: - The cost of a schoolchild ticket is 15% of the cost of an adult ticket. - 15% of 2800 rubles is 0.15 * 2800 = 420 rubles per schoolchild ticket.

2. Calculate the total cost of schoolchild tickets: - The group consists of 6 schoolchildren. - Multiply the cost of a schoolchild ticket by the number of schoolchildren in the group: 420 rubles * 6 = 2520 rubles.

3. Calculate the total cost of adult tickets: - The group consists of 4 adults. - Multiply the cost of an adult ticket by the number of adults in the group: 2800 rubles * 4 = 11200 rubles.

4. Calculate the total cost of tickets for the group: - Add the total cost of schoolchild tickets to the total cost of adult tickets: 2520 rubles + 11200 rubles = 13720 rubles.

Therefore, the total cost of tickets for the group, consisting of 6 schoolchildren and 4 adults, is 13720 rubles.
