13 The cost of 5 kg of potatoes is £3.20
The cost of \(\frac{1}{2}\) kg of carrots is 29p
Work out the total cost of 12 kg of potatoes and \(1\frac{1}{2}\) kg of carrots. [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| Alternative method 1 | ||
| \(3.2(0) \div 5\) or 0.64 or \(0.29 \times 3\) or 0.87 | M1 | oe eg working in pence |
| \(3.2(0) \div 5 \times 12 + 0.29 \times 3\) or 7.68 + 0.87 | M1dep | oe eg working in pence must be consistent units |
| 8.55 | A1 | condone £8.55p |
| Alternative method 2 | ||
| \(12 \div 5\) or 2.4 or \(5 \div 12\) or 0.41(6…) or 0.417 or 0.42 | M1 | |
| \(3.2(0) \times\) their \(2.4 + 0.29 \times 3\) or \(3.2(0) \div\) their \(0.41(6…) + 0.29 \times 3\) | M1dep | oe eg working in pence must be consistent units |
| 8.55 | A1 | condone £8.55p |
Additional guidance
Inconsistent units may be recovered in final answer
7.68 in working implies M1
