Calculation of Interest on Bank Account

To calculate the amount of money that will be on the bank account after one year, we need to consider the initial deposit of 21,000 rubles and the annual interest rate of 10%.

The formula to calculate the future value of an investment with compound interest is:

Future Value = Principal Amount × (1 + Interest Rate)^Number of Periods

In this case, the principal amount is 21,000 rubles, the interest rate is 10% (0.1 as a decimal), and the number of periods is 1 year.

Using this formula, we can calculate the future value of the bank account after one year:

Future Value = 21,000 × (1 + 0.1)^1

Calculating this equation, we find that the future value of the bank account after one year will be 23,100 rubles.

Please note that this calculation assumes that no additional deposits or withdrawals are made during the year and that the interest is compounded annually.
