1 u + 355 |
| Change |

- 131 |
| After |
1 u |
1 u + 224 |
(a)
After
Number of shortbreads that Gillian had = 1 u
Number of shortbreads that Mrs Heng had = 3 x 1 u = 3 u
Before
Number of shortbreads that Gillian baked = 1 u
Number of shortbreads that Mrs Heng baked = 1 u + 355
3 u = 1 u + 355 - 131
3 u - 1 u = 224
2 u = 224
1 u = 224 ÷ 2 = 112
Number of shortbreads that Gillian baked
= 1 u
= 112
(b)
Number of shortbreads that Mrs Heng baked
= 1 u + 355
= 112 + 355
= 467
Answer(s): (a) 112; (b) 467
