What are the opening balance, the definitions of debit and credit, total bank charges, the purpose of the deposit on 4/8, the reason for the nil ATM charge on 7/8, and the balance on 3/08 in words?

$$
\text{Total bank charges} = \text{R}48,00 + \text{R}7,50 + \text{R}7,50 + \text{R}0,00
$$
$$
\text{Total bank charges} = \boxed{\text{R}63,00}
$$

4. On 4/8, R765,56 was deposited into the account. It was for a Medical Aid refund.

5. The ATM withdrawal on 7/8 might have a nil (zero) charge because Pule could be within a certain number of free withdrawals allowed by the bank, or it was an ATM belonging to Pule's own bank, which often offers free transactions.

6. Step 1: Calculate A, the balance on 3/08.

   $$\text{Balance after Nu-metro movies} = \text{R}1\,396,98 - \text{R}72,00 = \text{R}1\,324,98$$ $$\text{A} = \text{R}1\,324,98 - \text{R}300,00$$ $$\text{A} = \boxed{\text{R}1\,024,98}$$

**One thousand twenty-four rand and ninety-eight cents**.

7. Step 1: Calculate the balance after the Insurance debit order. $\text{Balance after Insurance debit order} = \text{R}3\,976,98 - \text{R}137,98 = \text{R}3\,839,00$

$$
\text{B} = \text{R}3\,839,00 + \text{R}765,56
$$
$$
\text{B} = \boxed{\text{R}4\,604,56}
$$

8. Pule is having a current account (or cheque account).

9. ATM stands for Automated Teller Machine.
