Question

Кофейный сервиз, котрый стоит 700рублей, продаётся с 10-процентной скидкой. При покупке этого сервиза покупатель отдал кассиру 1000 рублей. Сколько рублей сдачи он должен получить?

Answer 1

Решаем методом пропорции.
700руб. - 100%
х руб. - 10%
700·10:100＝70 руб.
Раз сервиз продаётся по скидке, тогда цена сервиза будет меньше обычной.
700-70＝610 руб.- цена сервиза по скидке
Теперь ищем сдачу.
1000-610＝390 руб.- сдача

Answer 2

1)700 - 100%
x - 10%

100x=7000|:100
x=70
2) Т.е цена была 700, то вычитаем скидку (10 процентов) 700-70=630(цена сервиза)
3) 1000-630=370(р) - должен получить сдачи покупатель

Answer 3

Calculation of Change

To calculate the change the buyer should receive, we need to subtract the total cost of the coffee set with the discount from the amount of money the buyer gave to the cashier.

The coffee set is priced at 700 rubles and is sold with a 10% discount. Therefore, the discounted price of the coffee set is calculated as follows:

Discounted price = Original price - (Original price * Discount percentage)

Discounted price = 700 - (700 * 0.10) = 700 - 70 = 630 rubles.

The buyer gave the cashier 1000 rubles. To calculate the change, we subtract the discounted price from the amount given:

Change = Amount given - Discounted price

Change = 1000 - 630 = 370 rubles

Therefore, the buyer should receive 370 rubles in change.

Please note that the information provided is based on the assumption that the discount is applied to the original price of the coffee set. If there are any additional fees or taxes, they may affect the final amount of change received.
