| Scheme | Marks | Comments |
|---|---|---|
Method to compare, e.g.
| M1 | Ignore incorrect units or lack of units for M, A and E marks Needs to show comparing like quantity with like, unless considering larger quantities where working shows a greater quantity for less money at Fairmart (e.g. 4950g with 5000g) |
Accurate comparison calculation, e.g.
| A1 | In cost per kg in SuperM, allow truncation of (1000 ÷ 450 =) 2.222.... to 1 or more decimal places to give 59.4, 59.94, 59.994, etc when × 27(p) Accept comparison given in pence (see the tables below) |
| Conclusion, e.g. ‘(Buying carrots from) FairMart (is better value for money.) | E1 | FT for ‘their costs’ provided M1 previously awarded |
