| Answer | Mark | Notes |
|---|---|---|
| 85.50 | 2 | M1 for \(2 \times 12.75 + 3 \times 20\) or \(12.75 + 3 \times 20\) (= 72.75) A1 for 85.5(0) |
| Answer | Mark | Notes |
|---|---|---|
| 16 | 3 | M1 (ft from (a)) for subtracting cost of 1 or 2 or 5 lessons from 305.50 \(305.50 - \text{“}2 \times 12.75\text{”}\) (= 280) or \(305.50 - \text{“}85.50\text{”}\) (= 220) or \(305.50 - 12.75\) (= 292.75) M1 for \(\text{``}280\text{''} \div 20\) (= 14) or \(\text{``}220\text{''} \div 20\) (= 11) or \(292.75 \div 20\) A1 cao OR M1 for adding 20s to cost of 1 or 2 or 5 lessons eg 12.75 or “2×12.75” or “85.50” and intention to add on 20s or \(14 \times 20\) or \(11 \times 20\) M1 for “2×12.75” or “85.50” and adding 20s to within 20 of 305.50 A1 cao |
