| Answer | Mark | Mark scheme |
|---|---|---|
| £73.60 or 7360p | M1 | for \(89198 - 88738\ (= 460)\) OR for showing \(89198 \times 16\) or \(88738 \times 16\) OR for showing \((89198 + 88738) \times 16\) |
| M1 | for showing \(\text{``}460\text{''} \times 16\) OR for showing \(89198 \times 16 - 88738 \times 16\) | |
| M1 | (dep on M1) for a complete method of multiplication with relative place value correct including an intention to add all the appropriate elements of the calculation eg, 2 lines of the 1st method, internal numbers of grids, or complete structure shown of partitioning methods. | |
| A1 | for £73.6(0) or 7360p SC B3 for an answer with digits 736 with incorrect or missing units |

\(89198 \times 16 = 1427168\)
\(88738 \times 16 = 1419808\)
\((89198 + 88738) \times 16 = 2846976\)
Accept in any units, correct figures would imply previous mark
