| Rulers 85p each | Pens £3.50 each |
Jenny buys 5 rulers and 2 pens.
She works out how much she should pay.
| \(5 \times 85\text{p} = £4.25\) \(2 \times £3.50 = £6.10\) \(\text{Total} = £10.35\) |
Jenny’s total is wrong.
What mistake has she made?
Include the correct total in your answer. [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| Correct indication of mistake | B1 | eg (6.10) should be 7(.00) or \(2 \times 3.5(0)\) (= 7.(00)) or cost of pens is wrong |
| 11.25 | B1 |
Additional guidance
| Accept any correct indication of mistake eg two lots of 50p don’t equal 10p | |
| Condone (£) 11.25 p for second B1 | |
| Any reference to cost of rulers (words or calculations) being incorrect cannot score first B1 | |
| Response only references the decimal points not being lined up correctly | B0 |
