1 u + 322 |

- 188 |
| After |
1 u |
1 u + 134 |
(a)
After
Number of croissants that Hazel had = 1 u
Number of croissants that Mrs Fong had = 3 x 1 u = 3 u
Before
Number of croissants that Hazel baked = 1 u
Number of croissants that Mrs Fong baked = 1 u + 322
3 u = 1 u + 322 - 188
3 u - 1 u = 134
2 u = 134
1 u = 134 ÷ 2 = 67
Number of croissants that Hazel baked
= 1 u
= 67
(b)
Number of croissants that Mrs Fong baked
= 1 u + 322
= 67 + 322
= 389
Answer(s): (a) 67; (b) 389
