Answer 2

Calculation of Interest on a Time Deposit

To calculate the amount of money that will be on the account after one year, we need to consider the interest rate and the initial deposit.

Given that the Sberbank offers a 20% annual interest rate on the time deposit, and the initial deposit is 800 rubles, we can calculate the interest earned and add it to the initial deposit.

The formula to calculate the interest earned on a time deposit is:

Interest = Initial Deposit * Interest Rate

Substituting the values into the formula:

Interest = 800 rubles * 20%

To calculate the interest, we need to convert the percentage to a decimal by dividing it by 100:

Interest = 800 rubles * 0.20

Calculating the interest:

Interest = 160 rubles

Now, we can add the interest earned to the initial deposit to find the total amount on the account after one year:

Total Amount = Initial Deposit + Interest

Substituting the values:

Total Amount = 800 rubles + 160 rubles

Calculating the total amount:

Total Amount = 960 rubles

Therefore, if no other transactions are made on the account, the account balance will be 960 rubles after one year.
