| Answer | Mark | Mark scheme |
|---|---|---|
| No, not enough milk (supported) | Process to find amount needed (starting from recipe quantities) | |
| P1 | for a correct process to find amount needed of one ingredient, eg \(100 \div 10 \times 15\) oe (= 150) or \(200 \div 10 \times 15\) oe (= 300) or \(100 \div 2 + 100\ (= 150)\) or \(200 \div 2 + 200\ (= 300)\) or \(40 \div 2 \times 3\) oe (= 60) or \(2 \div 2 \times 3\) oe (= 3) or scale factor of 1.5 seen | |
| P1 | for a correct process to find amount needed of all the ingredients, eg \(100 \div 10 \times 15\) oe (= 150) and \(200 \div 10 \times 15\) oe (= 300) and \(40 \div 10 \times 15\) oe (= 60) and \(2 \div 10 \times 15\) oe (= 3) | |
| C1 | for statement that there is not enough milk with supporting evidence | |
| OR Process to find quantity of pancakes that can be made (working from the quantities of ingredients available) | ||
| P1 | for a correct process to find the number of pancakes that can be made with one ingredient, eg \(200 \div 100 \times 10\) oe (= 20) or \(250 \div 200 \times 10\) oe (= 12.5) or \(70 \div 40 \times 10\) oe (= 17.5) or \(5 \div 2 \times 10\) oe (= 25) | |
| P1 | for a correct process to find the number of pancakes all ingredients could produce eg \(200 \div 100 \times 10\) oe (= 20) and \(250 \div 200 \times 10\) oe (= 12.5) and \(70 \div 40 \times 10\) oe (= 17.5) and \(5 \div 2 \times 10\) oe (= 25) | |
| C1 | for statement that there is not enough milk with supporting evidence |
Additional guidance
C1 (both methods): Must have correct figures for all ingredients, but it is not necessary to comment on the other ingredients.
Any comment on the other ingredients must be correct.
Second method, first P1: Award this mark for a complete process to find the amount of ingredients for a quantity of pancakes that uses all of one of the ingredients eg process to find amount of ingredients for 20 pancakes (flour).
