Пошаговое объяснение:
Это называется - сложные проценты.
Формула сложных процентов:
C = В*(1 + с)ⁿ, где:
С - сумма в конце срока.
В = 38000 рублей - вклад
с = 7,8% = 0,078 - ставка вклада.
n = 3 - срок хранения вклада.
Вычисляем.
С = 3800*(1,078)³ = 38000*1,253 = 47603,61 руб ≈
≈ 47604 руб - сумма - ответ
Ставка в расчете суммы вычислена более точно -1,2527266.
