| Before |
1 u |
1 u + 497 |

- 175 |
| After |
1 u |
1 u + 322 |
(a)
After
Number of croissants that Lynn had = 1 u
Number of croissants that Mrs Pang had = 3 x 1 u = 3 u
Before
Number of croissants that Lynn baked = 1 u
Number of croissants that Mrs Pang baked = 1 u + 497
3 u = 1 u + 497 - 175
3 u - 1 u = 322
2 u = 322
1 u = 322 ÷ 2 = 161
Number of croissants that Lynn baked
= 1 u
= 161
(b)
Number of croissants that Mrs Pang baked
= 1 u + 497
= 161 + 497
= 658
Answer(s): (a) 161; (b) 658
