**2.3 Calculation of Percentage**  
Phindi scored 18 marks out of 30. The percentage is calculated as:  
$$
\text{Percentage} = \left(\frac{18}{30}\right) \times 100\%
$$  
Simplify the fraction:  
$$
\frac{18}{30} = 0.6
$$  
Thus,  
$$
0.6 \times 100\% = 60\%
$$

**2.4 Cost per Kilogram of Beef**  
If 6 kilograms of beef cost R179.90, then the cost per kilogram is:  
$$
\text{Cost per kg} = \frac{R179.90}{6}
$$  
Performing the division:  
$$
\frac{R179.90}{6} \approx R29.98
$$  
So, one kilogram of beef costs approximately R29.98.

**2.5 Value for Money Comparison for Potatoes**  
For half a kilogram of potatoes costing R4.50:  
$$
\text{Unit Price} = \frac{R4.50}{0.5\, \text{kg}} = R9.00 \text{ per kg}
$$

For 5 kilograms of potatoes costing R35:  
$$
\text{Unit Price} = \frac{R35}{5\, \text{kg}} = R7.00 \text{ per kg}
$$

Since R7.00 per kg is less than R9.00 per kg, the option of 5 kg for R35 is better value for money.
**2.3** Phindi scored **60%** on the test. **2.4** One kilogram of beef costs approximately **R29.98**. **2.5** Buying **5 kg of potatoes for R35** is better value for money.
