Answer 2

Calculating Deposit for 10% Annual Interest

To calculate the amount of money needed to be deposited in the bank account to receive a specific amount of profit at a given interest rate, we can use the following formula:

Interest = Principal × Rate × Time

Where: - Interest is the amount of profit earned - Principal is the initial amount of money deposited - Rate is the annual interest rate (in decimal form) - Time is the time period for which the money is deposited (in years)

In this case, the annual interest rate is 10% (0.10 in decimal form), and the desired profit is 800 UAH. We can use this information to calculate the required principal amount.

Calculation

Using the formula, we can rearrange it to solve for the principal:

Principal = Interest / (Rate × Time)

Substituting the given values: Principal = 800 / (0.10 × 1)

Result

Calculating the principal: Principal = 800 / 0.10 = 8000 UAH

Therefore, to receive 800 UAH in profit after one year at a 10% annual interest rate, one would need to deposit 8000 UAH into the bank account.
