3.1.1 The statement date is 01/03/2019, and all transactions listed are from February 2019. The statement belongs to the month of February. 3.1.2 To calculate the total bank fees, sum all the amounts in the "Bank Fee" column: $$ \text{Total Bank Fees} = 1.90 + 5.10 + 16.50 + 5.10 + 1.90 + 1.90 + 1.90 + 1.90 $$ $$ \text{Total Bank Fees} = 36.20 $$ The total bank fees paid during the month are $\boxed{\text{R } 36.20}$. 3.1.3 To calculate the value of A, subtract the debit amount and the bank fee from the previous balance. Previous balance (05/02/2019) = $\text{R } 4426.09$ Debit (07/02/2019, Cash ATM) = $\text{R } 3300.00$ Bank Fee (07/02/2019) = $\text{R } 16.50$ $$ \text{Value A} = 4426.09 - 3300.00 - 16.50 $$ $$ \text{Value A} = 1109.59 $$ The value of A is $\boxed{\text{R } 1109.59}$. 3.1.4 An overdraft occurs when the balance becomes negative. Looking at the "Balance" column, the balance becomes negative on 16/02/2019 after the "Cash POS" transaction. Date of overdraft: 16/02/2019 Amount of overdraft: R 28.95 3.1.5 To calculate the value of B, which is a deposit, add the deposit amount to the balance before the transaction to get the balance after the transaction. Balance before deposit (16/02/2019, after Cash POS) = $\text{R } -28.95$ Balance after deposit (16/02/2019, after Deposit P. West) = $\text{R } 831.40$ $$ \text{Balance after} = \text{Balance before} + \text{Deposit (B)} $$ $$ 831.40 = -28.95 + \text{B} $$ $$ \text{B} = 831.40 + 28.95 $$ $$ \text{B} = 860.35 $$ The value of B is $\boxed{\text{R } 860.35}$. 3.1.6 To determine the percentage of interest earned, divide the interest amount by the balance just before the interest was applied, and multiply by 100. Interest earned (28/02/2019) = $\text{R } 6.45$ Balance before interest (27/02/2019) = $\text{R } 11375.45$ $$ \text{Percentage of interest} = \left( \frac{\text{Interest earned}}{\text{Balance before interest}} \right) \times 100 $$ $$ \text{Percentage of interest} = \left( \frac{6.45}{11375.45} \right) \times
