1. **State the problem:** We need to find the total cost of sending parcels with given weights using the postage rate table. 2. **Postage rates:** - Up to 1 kg: 6.50 - Up to 3 kg: 9.80 - Up to 5 kg: 12.60 - Up to 10 kg: 17.60 3. **Determine cost per parcel based on weight:** (i) 3.4 kg → falls under 5 kg category → cost = 12.60 (ii) 1.6 kg → falls under 3 kg category → cost = 9.80 (iii) 7.1 kg → falls under 10 kg category → cost = 17.60 (iv) 4.8 kg → falls under 5 kg category → cost = 12.60 4. **Calculate total cost for each case:** (i) 2 parcels × 12.60 = $$2 \times 12.60 = 25.20$$ (ii) 4 parcels × 9.80 = $$4 \times 9.80 = 39.20$$ (iii) 1 parcel × 17.60 = $$1 \times 17.60 = 17.60$$ (iv) 2 parcels × 12.60 = $$2 \times 12.60 = 25.20$$ 5. **Final answers:** - (i) 25.20 - (ii) 39.20 - (iii) 17.60 - (iv) 25.20 Each total is the cost to send the parcels as described.
