Пример №30 из задания 3

Набор полотенец, который стоил \(350\) рублей, продаётся со скидкой \(4\%\). Сколько рублей стоят два набора полотенец со скидкой?


Решение

Скидка на один набор полотенец составляет \(350\div100\cdot4=14\) рублей.

Значит, один набор полотенец со скидкой будет стоить \(350-14=336\) рубля.

Соответственно, два набора полотенец со скидкой будут стоить \(336\cdot2=672\) рублей.

Ответ: \(672\).
