| Answer | Mark | Mark scheme |
|---|---|---|
| 15.5(0) | P1 | for a correct process to find the cost of some teas only or some coffees only eg (2 teas =) \(8.50 - 4.50\ (= 4)\) or (2 coffees =) \(3 \times 4.50 - 8.50\ (= 5)\) |
| P1 | for a process to find the cost of one tea or four teas, eg (1 tea =) \(\text{``}4\text{''} \div 2\ (= 2)\) or (4 teas =) \(\text{``}4\text{''} \times 2\ (= 8)\) | |
| P1 | for a process to find cost of one coffee or three coffees, eg (1 coffee =) \(4.50 - \text{``}2\text{''}\ (= 2.50)\) or \(8.50 - \text{``}2\text{''} \times 3\ (= 2.50)\) or \(1.5 \times \text{``}5\text{''}\ (= 7.50)\) | |
| P1 | for a complete process, eg \(\text{``}2\text{''} \times 4 + \text{``}2.50\text{''} \times 3\) | |
