Question

Вот вещь 380 руб скидка 8%,=> 380*0.08, и вот вопрос, почему умножить, и почему мы получаем 30.4 .

Answer 1

Умножаем, потому что составляем пропорцию:

380 - 100%

x - 8%

x = 380*8/100 = 380*0,08 = 30,4

30,4 - это получается по умножению на калькуляторе, или в столбик.

Это размер скидки.

380 - 30,4 = 349,6 руб. - это цена вещи после скидки.

Answer 2

To calculate the discount amount, you need to multiply the original price by the discount percentage. Here's how it works:

1. Original price: 380 rubles
2. Discount percentage: 8%

To calculate the discount amount:

Discount Amount = Original Price * Discount Percentage Discount Amount = 380 * 0.08

Now, let's do the math:

Discount Amount = 30.4 rubles

The result, 30.4 rubles, is the discount amount. This means you would get a discount of 30.4 rubles on the original price of 380 rubles. To find the final price after the discount, you would subtract the discount amount from the original price:

Final Price = Original Price - Discount Amount Final Price = 380 - 30.4 Final Price = 349.6 rubles

So, the final price after applying an 8% discount to an item that costs 380 rubles would be 349.6 rubles.
