В сберегательном банке денежный вклад увеличился на 10% за год. Сколько денег вкладчик положил на вклад, если через год у него на вкладе 44000 руб.?

Ответы

Автор ответа: grigopiy

х - первоначальный вклад в банке

0,1х - прирост денег за год

х + 0,1х = 44000

1,1х = 44000

х = 44000 : 1,1

х = 40000 руб.

Ответ: вкладчик положил на вклад 40000 рублей
