1000 g plain flour
225 g chocolate chips
What is the greatest number of biscuits Lucas can make?
You must show your working. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| 90 | P1 | for a process to find the number of batches for at least 2 ingredients, eg \(900 \div 225\ (= 4)\) or \(1000 \div 110\ (= 9.09..)\) or \(1000 \div 275\) (= 3.6.....) or \(225 \div 75\ (= 3)\) OR A full method to find the maximum number of biscuits for 1 ingredient eg \(900 \div 225 \times 30\) OR Amount required for 1 biscuit for at least 2 ingredients eg \(225 \div 30\ (= 7.5)\) or \(110 \div 30\ (= 3.6..)\) or \(275 \div 30\ (= 9.1..)\) or \(75 \div 30\ (= 2.5)\) OR Amount required for 3 batches for at least 2 ingredients eg \(225 \times 3\ (= 675)\) or \(110 \times 3\ (= 330)\) or \(275 \times 3\ (=825)\) or \(75 \times 3\ (= 225)\) |
| P1 | (dep P1) for a complete process to find the maximum number of biscuits after considering at least 3 different ingredients eg \(\text{``}3\text{''} \times 30\) | |
| A1 | (dep P2) cao from fully correct working |
Additional guidance
They must use their smallest multiplier after considering at least 3 different ingredients
90 without working award no marks
