Question

Банк выплачивает доход из расчета 7% вложенной суммы в год. Сколько денег окажется на счёте через 2 года, если на него положили 10000 рублей??

Answer 1

7%= 10000*7/100=700руб
2*700=1400

Answer 2

10000:100*7=700
10000+700=10700
10700:100*7=749
10700+749=11449
Ответ 11449

Answer 3

Calculation of the Account Balance after 2 Years

To calculate the account balance after 2 years with an annual interest rate of 7%, we can use the formula for compound interest:

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

Where: - A is the final account balance - P is the initial principal amount (in this case, 10,000 rubles) - r is the annual interest rate (7% or 0.07) - n is the number of times interest is compounded per year (assuming it is compounded annually, n = 1) - t is the number of years (2 years)

Plugging in the values, we get:

A = 10,000(1 + 0.07/1)^(1*2)

Simplifying the equation:

A = 10,000(1.07)^2

Calculating the exponent:

A = 10,000(1.1449)

Finally, calculating the account balance:

A ≈ 11,449 rubles

Therefore, the account balance after 2 years, with an initial deposit of 10,000 rubles and an annual interest rate of 7%, would be approximately 11,449 rubles.

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