Mr Warren Heyns received his Titanium credit card statement for his account at Standard Bank, dated 9 September 2023 - NSC Mathematical Literacy - Question 2 - 2024 - Paper 1

One valid reason for omitting some numbers from the account number could be for security reasons to protect personal information.

To determine the available money to spend, we start with an initial balance:

Available Money = Initial Balance - Outstanding Transactions

Assuming the initial balance is R20 000,00 and the total outstanding authorisations amount to R11 676,22:

Available Money = R20 000,00 - R11 676,22 = R8 323,78.

The amount paid to Caltex was R1 376,15 for 54,1365 litres. The price per litre is calculated as follows:

Price per Litre = Total Amount Paid / Litres Purchased

Price per Litre = R1 376,15 / 54,1365 = R25,42.

Let the original price be represented as P. The discounted price is given by:

Discounted Price = P - (17.5% of P)

discounted Price = P × (1 - 0.175)

Let the discounted price be R3 999,99. We can express it as:

P × 0.825 = R3 999,99

Solving for P gives:

P = R3 999,99 / 0.825 = R4 848,4848, approximately R4 848,48.
