| Answer | Mark | Notes |
|---|---|---|
| Offer 1 (supported) | P1 | for a process to find the cost of a number of lessons in Offer 1, eg. \(24 \times (12 - 1)\ (= 264)\) or for a process to find 5% (or 95%) of an appropriate amount, eg. \(24 \times 0.05\ (= 1.20)\) or \(24 \times 0.95\ (= 22.80)\) in Offer 2 |
| P1 | for a complete process leading to values to be used for comparison, eg. \(24 \times (12 - 1)\ (= 264)\) and \(24 \times 0.95 \times 12\ (= 273.60)\) | |
| C1 | Offer 1 and correct values, eg. (£)264 and (£)273.6(0) used for comparison |
