### **1.1 Total monthly expenses for the body corporate**

1. **Monthly expenses:**
   - Water: ₱680
   - Refuse removal: ₱330
   - Sewerage: ₱480

   Total monthly operational expenses:
   \[
   680 + 330 + 480 = ₱1,490
   \]

2. **Annual expenses converted to monthly:**
   - Rates and taxes:
     \[
     \frac{44,600}{12} = ₱3,716.67
     \]
   - Maintenance:
     \[
     \frac{24,000}{12} = ₱2,000
     \]

3. **Total monthly expenses:**
   \[
   ₱1,490 + ₱3,716.67 + ₱2,000 = ₱7,206.67
   \]

---

### **1.2 Amount each owner must pay towards monthly expenses**

1. **Total floor area:**
   \[
   200 + 350 + 350 + 450 = 1,350 \, \text{m}^2
   \]

2. **Proportion of floor area:**
   - Flat 1: \( \frac{200}{1350} \)
   - Flat 2: \( \frac{350}{1350} \)
   - Flat 3: \( \frac{350}{1350} \)
   - Flat 4: \( \frac{450}{1350} \)

3. **Monthly share for each owner:**
   Multiply the proportion by the total monthly expense (\(₱7,206.67\)):

   - Flat 1:
     \[
     \frac{200}{1350} \times 7,206.67 = ₱1,067.00
     \]
   - Flat 2:
     \[
     \frac{350}{1350} \times 7,206.67 = ₱1,868.33
     \]
   - Flat 3:
     Same as Flat 2, ₱1,868.33.
   - Flat 4:
     \[
     \frac{450}{1350} \times 7,206.67 = ₱2,403.00
     \]

#### **1.3.1 Total annual wage for the gardener**

1. **Weekly pay:**
   Gardener works once a week, earning ₱300 per day:
   \[
   ₱300 \times 52 = ₱15,600

   \[
   ₱15,600 + ₱3,000 = ₱18,600
   \]

#### **1.3.2 Ratio of gardener's wage to annual maintenance**

1. Gardener's total wage:
   \[
   ₱18,600
   \]
2. Annual maintenance:
   \[
   ₱24,000
   \]
3. Ratio:

   \frac{18,600}{24,000} = 0.775 \, \text{or} \, 77.5\%
   \]
