| Answer | Mark | Mark scheme |
|---|---|---|
| 30 | P1 | for full process to find the number of bags sold eg \(5 \times 1000 \div 250\ (= 20)\) OR for process to find selling price of 1 kg of sweets eg \(0.65 \times 4\ (= 2.60)\) |
| P1 | for [number of bags] \(\times\ 0.65\) or \(\text{``}20\text{''} \times 0.65\ (= 13)\) or \(\text{``}2.60\text{''} \times 5\ (= 13)\) OR for \(10 \div \text{``}20\text{''}\) oe (= 0.50) OR for \(0.65 \times 4\ (= 2.60)\) and \(10 \div 5\ (= 2)\) | |
| P1 | (dep on previous P1) for a process to find the percentage profit eg \((\text{``}13\text{''} - 10) \div 10 \times 100\) or \((0.65 - \text{``}0.50\text{''}) \div \text{``}0.50\text{''} \times 100\) or \((\text{``}2.60\text{''} - \text{``}2\text{''}) \div \text{``}2\text{''} \times 100\) OR \(\text{``}13\text{''} \div 10 \times 100\ (= 130)\) oe | |
| A1 | cao |
Additional guidance
This could be by repeated addition
Calculations can be in £ or pence
[number of bags] can only come from
\(5 \times 10 \div 250\ (= 0.2)\)
or \(5 \times 100 \div 250\ (= 2)\)
or \(5 \div 250\ (= 0.02)\)
3/10 or 0.3 is not enough but should be awarded 2 marks
Award P3 for 130(%)
