Let's go through the questions step-by-step using the account statement provided.
### 1.5.1 Write down the opening balance of the account.
The opening balance of the account can be found in the statement at the beginning. It is listed as:
[tex]\[ \text{Opening balance} = R 1000.61 \][/tex]
### 1.5.2 How much did Katlego pay for this month?
From the account statement, it seems that multiple payments and deductions were made. Katlego specifically paid an amount which is listed as "ATMM payment":
[tex]\[ \text{ATMM payment} = R 200.00 \][/tex]
### 1.5.3 Which deduction on this account is not a necessity?
Among the listed deductions, we have:
- Interest
- ATMM payment
- Account protection plan
- Lifestyll magazine
Out of these, the "Lifestyll magazine" is most likely a non-necessity as magazine subscriptions are generally considered non-essential expenses. Hence:
[tex]\[ \text{Non-necessity deduction} = R 25.00 \][/tex]
### 5.4 Determine the interest as a percentage of the opening balance.
To find the interest as a percentage of the opening balance, we use the formula:
[tex]\[ \text{Interest Percentage} = \left( \frac{\text{Interest}}{\text{Opening Balance}} \right) \times 100 \][/tex]
From the statement:
[tex]\[ \text{Interest} = R 23.73 \][/tex]
[tex]\[ \text{Opening Balance} = R 1000.61 \][/tex]
Plugging in these values:
[tex]\[ \text{Interest Percentage} = \left( \frac{23.73}{1000.61} \right) \times 100 = 2.37\% \][/tex]
So, the interest as a percentage of the opening balance is approximately 2.37%.
To summarize:
1.5.1 The opening balance of the account is R 1000.61.
1.5.2 Katlego paid R 200.00 for this month.
1.5.3 The deduction on this account that is not a necessity is the Lifestyll magazine subscription, which costs R 25.00.
5.4 The interest as a percentage of the opening balance is approximately 2.37%.
