Question

Банк начисляет 8% годовых. Елена открыла счёт на 42.500. Какая сумма будет у Елены через два года?

Answer 1

Формула для решения:

42500 : 100 · 8 · 2.

Но 42500 : 100 · 8 можно заменить на 42500 · 0.08 (результат будет тот же), так как 1% = 0.01.

Итак, получаем:

42500 · 0.08 · 2 = 3400 · 2 = 6800.

Теперь складываем годовые с начальной суммой и получаем: 42500 + 6800 = 49300.

Ответ: 49300 р.

Answer 2

42500*1,08=45 900 через год
45 900*1,08=49 572 через 2 года

1,08 =100 %+ 8 % =108 % 

Answer 3

Calculation of Interest

To calculate the amount Elena will have after two years with an annual interest rate of 8%, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

Where: - A is the final amount - P is the principal amount (initial deposit) - r is the annual interest rate (expressed as a decimal) - n is the number of times interest is compounded per year - t is the number of years

In this case, Elena's initial deposit is 42,500 rubles, the annual interest rate is 8%, and the time period is two years.

Calculation:

Using the formula, we can calculate the final amount Elena will have after two years:

A = 42,500(1 + 0.08/1)^(1*2)

Let's calculate this:

A = 42,500(1 + 0.08)^2

A = 42,500(1.08)^2

A ≈ 42,500(1.1664)

A ≈ 49,548 rubles

Therefore, Elena will have approximately 49,548 rubles after two years.

Please note that this calculation assumes the interest is compounded annually. If the interest is compounded more frequently (e.g., quarterly or monthly), the final amount may be slightly different.
