1 u + 349 |

- 177 |
| After |
1 u |
1 u + 172 |
(a)
After
Number of croissants that Linda had = 1 u
Number of croissants that Mrs Chew had = 3 x 1 u = 3 u
Before
Number of croissants that Linda baked = 1 u
Number of croissants that Mrs Chew baked = 1 u + 349
3 u = 1 u + 349 - 177
3 u - 1 u = 172
2 u = 172
1 u = 172 ÷ 2 = 86
Number of croissants that Linda baked
= 1 u
= 86
(b)
Number of croissants that Mrs Chew baked
= 1 u + 349
= 86 + 349
= 435
Answer(s): (a) 86; (b) 435
