Question

Билет на выставку стоит 400 руб. Студентам скидка 15%. Выставку посетило 20 студентов. Найти какую сумму внесли студенты.

Answer 1

Билет для студента: 0,85*400=340 р
20*340=6800 руб

Answer 2

400 руб * 0,15 % = 60 руб скидка студентам
400 руб - 60 руб= 340руб будет стоить билет
билет умножаем на количество студентов и получится стоимость билетов.
340 руб * 20 человек = 6800 руб
Ответ : 6800 руб

Answer 3

Calculation of the Amount Paid by Students for the Exhibition

To calculate the amount paid by the students for the exhibition, we need to consider the ticket price and the discount given to students.

Given: - Ticket price: 400 rubles - Student discount: 15% - Number of students: 20

To find the amount paid by the students, we can follow these steps:

1. Calculate the discounted ticket price for students: - Discounted ticket price = Ticket price - (Ticket price * Discount percentage) - Discounted ticket price = 400 - (400 * 0.15) = 400 - 60 = 340 rubles

2. Calculate the total amount paid by the students: - Total amount paid by students = Discounted ticket price * Number of students - Total amount paid by students = 340 * 20 = 6800 rubles

Therefore, the students paid a total of 6800 rubles for the exhibition.
