You must show how you get your answer. (3)
| Answer | Mark | Mark scheme |
|---|---|---|
| Yes and 750 | P1 | for beginning to work with proportion eg \(60 \div 20\ (= 3)\) or \(900 - 250\ (= 650)\) or \(250 \div 20\ (= 12.5 \text{ oe})\) or \(900 \div 60\ (= 15)\) |
| P1 | for a complete process to see if there is enough peanut butter eg \(\text{``}3\text{''} \times 250\ (= 750)\) or \(900 \div \text{``}3\text{''}\ (= 300)\) or \(\text{``}650\text{''} - 250 - 250\ (= 150)\) oe or \(\text{``}12.5\text{''} \times 60\ (= 750)\) or for a complete process to work out how many cookies he can make eg \(900 \div \text{``}12.5\text{''}\ (= 72)\) or for process to work out how much peanut butter is needed for one cookie and how much peanut butter he can use per cookie eg \(250 \div 20\ (= 12.5 \text{ oe})\) and \(900 \div 60\ (= 15)\) | |
| C1 | Yes and accurate figure to compare eg 750 (g needed) or 150 (g over) or 300 (g per batch available) or 72 (cookies can be made) or 12.5 (g peanut butter per cookie needed) and 15 (g peanut butter per cookie available) |
Additional guidance
Sugar = 600 (g) or Small eggs = 6 (eggs) implies P1
Sight of 750 gains P2
