### **4. Number of Learners a School Can Enrol**

**Given:**
- **Number of Teachers:** 12
- **Learner-to-Teacher Ratio:** 30:1

**To Find:** Total number of learners the school can enrol.

**Solution:**
The learner-to-teacher ratio of 30:1 means there are 30 learners for every 1 teacher.

**Calculation:**
$$
\text{Total Learners} = \text{Number of Teachers} \times \text{Learners per Teacher}
$$
$$
\text{Total Learners} = 12 \times 30 = 360
$$

**Answer:** The school can enrol **360 learners**.

### **5. Paint Cost Calculations**

#### **a) Cost of Fifteen Litres of Paint**

**Given:**
- **Cost for 5 Litres:** R210

**To Find:** Cost for 15 litres.

**Solution:**
First, determine the cost per litre.

$$
\text{Cost per Litre} = \frac{\text{Total Cost}}{\text{Number of Litres}} = \frac{R210}{5} = R42 \text{ per litre}
$$

Now, calculate the cost for 15 litres:

$$
\text{Cost for 15 Litres} = 15 \times R42 = R630
$$

**Answer:** Fifteen litres of paint cost **R630**.

#### **b) Checking if the Total Price is Within Mr. Jones's Budget**

**Given:**
- **Mr. Jones's Budget:** R650
- **Total Cost of 15 Litres:** R630

**To Find:** Whether R630 is within the budget of R650.

**Solution:**
Compare the total cost with the budget.

$$
R630 \leq R650
$$

Since **R630** is less than **R650**, the total price is within Mr. Jones's budget.

**Answer:** **Yes**, the total price of R630 is within Mr. Jones's budget of R650.
