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 each individual and then sum them up.

Given the following information: - The cost of an adult ticket is 820 rubles. - The cost of a ticket for a schoolchild is 50% of the cost of an adult ticket. - The group consists of 20 schoolchildren and 2 adults.

Let's calculate the cost of tickets for each individual:

- Cost of an adult ticket: 820 rubles. - Cost of a schoolchild ticket: 50% of 820 rubles = 410 rubles.

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

- Total cost of adult tickets: 2 adults * 820 rubles/adult = 1640 rubles. - Total cost of schoolchild tickets: 20 schoolchildren * 410 rubles/schoolchild = 8200 rubles.

Finally, we can calculate the total cost of tickets for the entire group:

- Total cost of tickets for the group: Total cost of adult tickets + Total cost of schoolchild tickets = 1640 rubles + 8200 rubles = 9840 rubles.

Therefore, the total cost of tickets for the entire group is 9840 rubles.
