| Answer | Mark | Mark scheme |
|---|---|---|
| 4 pint with correct figures | P1 | for a process to find the price for one deal, eg 6 pints on 1st deal, \(75 \times 2\ (= 150)\) or 8 pints on 2nd deal, \(128 \times 1.5\ (= 192)\) oe |
| P1 | for a process to find the price for both deals, eg 6 pints on 1st deal, \(75 \times 2\ (= 150)\) and 8 pints on 2nd deal, \(128 \times 1.5\ (= 192)\) oe | |
| P1 | for a process to find the cost per pint for both deals, eg \(\text{``}150\text{''} \div 6\ (= 25)\) and \(\text{``}192\text{''} \div 8\ (= 24)\) or for prices for a consistent number of pints for both deals eg for 2 pints \(\text{``}1.5\text{''} \div 3\ (=0.5)\) and \(\text{``}1.92\text{''} \div 4\ (= 0.48)\) or a comparison using a unit price eg \(\text{``}150\text{''} \div 6 \times 8\ (= 200)\) and \(128 \times 1.5\ (= 192)\) oe | |
| C1 | “4 pint” with two correct comparative costs calculated making full use of both offers |
Additional guidance
Accept in mixed units of pence and pounds
Might look at a price difference for a consistent number of pints
“4 pint” can be indicated in words or other indication
