Question

Стоимость чайника после уценки на 20%составила 4000рублей .какова была первоначальная цена чайника? ответ дайте в рублях

Answer 1

1)100%-20%=80%
2)Составим пропорцию: 80% - 4000 руб
                                    100% - Х руб , отсюда Х=4000*100÷80=5000руб

Answer 2

Calculation of the Initial Price of the Kettle

To calculate the initial price of the kettle, we need to determine the price before the 20% discount was applied.

Let's assume the initial price of the kettle is represented by the variable x in rubles.

The price after the 20% discount is given as 4000 rubles.

We can set up the following equation to solve for x:

x - 0.2x = 4000

Simplifying the equation, we have:

0.8x = 4000

Dividing both sides of the equation by 0.8, we find:

x = 4000 / 0.8 = 5000

Therefore, the initial price of the kettle was 5000 rubles.
