Question 12 is a money question! The answer to Q12.   £3.05 2 marks are awarded for a correct answer, even if no working out is shown. If the answer is incorrect but there is written evidence that appropriate working out has been done then one mark can be awarded. One mark can be awarded for incorrectly showing the answer e.g. £305 or £305p, but working must be shown for the award of one mark. Suggested method: This is quite a strange question as there are two possible approaches, the second of which hardly needs any working! Looking at the first approach, this would require finding the cost of the book that Dev bought. Take £1.05 from £5 leaves £3.95. This is probably best done mentally by taking £1 away and then taking 5p. (Watch out for silly slips such as recording £4.95.) Then the £3.95 can be taken from £7 to find the difference.  Again this is probably best done mentally by subtracting £4 and adjusting by 5p to leave £3.05 or by counting up. The second way is simpler: Joe handed over £2 more, plus the £1.05 change that Dev would have taken. £2 + £1.05 makes £3.05. Written working might just look like: 7 – 5 = 2 2 + 1.05 = 3.05.
