| 4.40 | 3 | M1 for a method to find the cost for one delivery method eg \(19 + 7 \times 0.7(0)\) (= 23.9(0)) or \(16 + 7 \times 0.5(0)\) (= 19.5(0)) M1 for a method to find the cost for both delivery methods and attempting to subtract eg \(23.90 - 19.50\) A1 cao Accept 4.4 OR M1 for method to find the difference between the two delivery costs eg \(19 - 16\) (= 3) and \(70 - 50\) (= 20) M1 for a method to find the “cost” using the differences eg \(\text{``}3\text{''} + 7 \times \text{``}20\text{''}\) A1 cao Accept 4.4 |

|---|---|---|
| 23 | 3 | M1 for \(25 - 16\) (= 9) M1 for a method to divide “9” by 0.50 (= 18) A1 cao OR M1 for starting with 16 and a method to add on 0.50s M1 for starting with 16 and adding on 0.50s to within 0.50 of 25 A1 cao |
