| Before |
1 u |
1 u + 404 |
| Change |

- 166 |
| After |
1 u |
1 u + 238 |
(a)
After
Number of puffs that Dana had = 1 u
Number of puffs that Mrs Peh had = 3 x 1 u = 3 u
Before
Number of puffs that Dana baked = 1 u
Number of puffs that Mrs Peh baked = 1 u + 404
3 u = 1 u + 404 - 166
3 u - 1 u = 238
2 u = 238
1 u = 238 ÷ 2 = 119
Number of puffs that Dana baked
= 1 u
= 119
(b)
Number of puffs that Mrs Peh baked
= 1 u + 404
= 119 + 404
= 523
Answer(s): (a) 119; (b) 523
