| e.g. $20 = £12.50 $100 = \(5 \times\) £12.50 = £62.50 £62.50 − 60 = £2.50 | £2.50 OR $4 | 3 | M1 for a correct method to convert $100 to £, e.g. \(5 \times\) ‘12.50’ (= 62.50) (‘12.50’ is their reading from the graph at $20) M1 (dep) for ‘62.50’ − 60 A1 for £2.5(0) (units must be stated) OR M1 for correct method to convert £60 to $, e.g. \(3 \times 32\) (=96) or ft their answer to part (a) M1 (dep) for 100 − ‘96’ A1 for $4 (units must be stated) |
