*4 Mr and Mrs Shankara and their 3 children go on a train journey.
Mr Shankara pays for 2 adult tickets and 3 child tickets.
The price of an adult ticket is £8.40
The price of a child ticket is half the price of an adult ticket.
Mr Shankara pays for the tickets with 3 ten pound notes.
Work out how much change he should get. (4)
| Answer | Mark | Notes |
|---|---|---|
| 60p | 4 | M1 for price of child ticket e.g. \(8.40 \div 2\) (= 4.20) M1 for a method to work out the total cost of the 2 adults e.g. \(2 \times 8.40\) (= 16.80) or of the 3 children e.g. \(\text{``}4.20\text{''} \times 3\) (= 12.60) or of the whole family e.g. \(2 \times 8.40 + 3 \times \text{``}4.20\text{''}\) (= 29.40) M1 for a complete method to work out the change e.g. \(3 \times £10 - \text{``}29.40\text{''}\) = (0.60) or \(3 \times £10 - (2 \times 8.40 + 3 \times \text{``}4.20\text{''})\) (= 0.60) C1 for change with correct money notation 60p or £0.60 (accept £0.60p) NB candidates may work in pence rather than pounds |
