Question

Футболка стоила 800 рублей. затем цена снижена на 15%. Сколько рублей сдачи с 1000 рублей должен получить покупатель при покупке этой футболки после снижения цены?

Answer 1

15% - это 0,15
800*0,15=120 руб. - на столько снизилась цена.
800-120=680 руб. - цена футболки после снижения.
1000-680=320 руб. - сдачи должен получить покупатель.

Answer 2

100% - 15% = 85% - новая цена футболки.
100% - 800 руб;
  85%  - х рубл.

100* х = 85* 800;
х  = 680 рублей - стала стоить футболка после уценки.

1000 - 680 =320 рублей сдачи

Answer 3

Calculation of Change and Amount of Change

To calculate the change in price and the amount of change, we need to follow these steps:

1. Determine the original price of the t-shirt, which is 800 rubles. 2. Calculate the discount amount by multiplying the original price by the discount percentage. In this case, the discount is 15%, so the discount amount is 800 * 0.15 = 120 rubles. 3. Subtract the discount amount from the original price to find the new price after the discount. The new price is 800 - 120 = 680 rubles. 4. Calculate the amount of change by subtracting the new price from the amount paid by the customer. In this case, the customer paid 1000 rubles, so the amount of change is 1000 - 680 = 320 rubles.

Therefore, the customer should receive 320 rubles as change when purchasing the t-shirt after the price reduction.

Note: The calculation assumes that the customer pays the exact amount without any additional charges or taxes.
