Answer 2

15%=0.15
3000*0.15 = 450 - денег надо ещё собрать школьникам

Answer 3

Calculation of the Additional Amount Needed

To calculate the additional amount of money needed by the students, we need to consider that the ticket prices increased by 15%. The students initially collected 3000 rubles for the tickets.

To find out the new price of the tickets after the increase, we can use the following formula:

New Price = Initial Price + (Initial Price * Increase Percentage)

In this case, the initial price is the amount of money the students collected, which is 3000 rubles, and the increase percentage is 15%.

Let's calculate the new price:

New Price = 3000 + (3000 * 0.15)

New Price = 3000 + 450

New Price = 3450 rubles

Therefore, the students need to collect an additional 3450 rubles to purchase the theater tickets at the increased price.
