| Working | Answer | Mark | Notes |
|---|---|---|---|
| \(400 \div 18 = 22(.2)\) \(499 \div 20 = 24(.95)\) or 25 \(600 \div 26 = 23(.07\ldots)\) (or equivalent in £) \(18 \div 4 = 4.5\) \(20 \div 4.99 = 4(.008\ldots)\) \(26 \div 6 = 4.3(333\ldots)\) | 18 pack with supporting working | 4 | M1 for a method that would result in at least two values that could be used to compare two packs M1 for a complete method that would result in values that could be used to compare all three packs A1 for all fully correct figures suitable for comparison C1 ft (dep on M2) for comparison of their values with a correct conclusion from their figures |
