Numeracy Foundation June 2018 Unit 1 Q6
6. Suzanna and her 2 friends are studying at Aberystwyth University.
They rent a 3-bedroom house together.
The 3 friends share the cost of the rent equally between them.
In April, the rent was £720 per month.
In October, the rent is to be increased by 15%.
How much rent will Suzanna pay in October? [4]
| Scheme | Marks | Comments |
|---|---|---|
| (Rent increase) 15/100 × (£)720 (£)108 | M1 A1 | Must be a full correct method to find 15% |
| (Rent in October ) (£)828 | B1 | FT 720 + ‘their derived 108’ correctly evaluated |
| (Suzanna pays) (£)276 | B1 | FT ‘their derived 828’ ÷ 3 correctly evaluated |
Alternative
| Scheme | Marks |
|---|---|
| Alternative ((£)720 ÷ 3 =) (£)240 | B1 |
| 15/100 × ‘their derived (£)240’ | M1 |
| = (£)36 | A1 |
| ‘their derived (£)240’ + ‘their derived (£)36’ = (£)276 | B1 |
The alternative is printed in italics in the original.
