Answer 2

1) To calculate the amount of money the depositor will have in their account after one year with a 7% annual interest rate, we can use the formula:

Final Amount = Initial Amount + (Initial Amount * Interest Rate)

In this case, the initial amount is 7,000,000 tenge and the interest rate is 7%. Plugging these values into the formula, we get:

Final Amount = 7,000,000 + (7,000,000 * 0.07)

Calculating this, we find that the depositor will have 7,490,000 tenge in their account after one year with a 7% annual interest rate.

2) To determine the initial amount deposited in the bank if the account balance increased by 520,000 tenge after one year with an 8% annual interest rate, we can use the formula:

Initial Amount = Final Amount / (1 + Interest Rate)

In this case, the final amount is the initial amount plus the interest earned, which is 520,000 tenge. The interest rate is 8%. Plugging these values into the formula, we get:

Initial Amount = 520,000 / (1 + 0.08)

Calculating this, we find that the initial amount deposited in the bank was 480,000 tenge.

Please note that these calculations assume that the interest is compounded annually.
