1 u + 461 |
| Change |

- 185 |
| After |
1 u |
1 u + 276 |
(a)
After
Number of puffs that Hazel had = 1 u
Number of puffs that Mrs Leng had = 4 x 1 u = 4 u
Before
Number of puffs that Hazel baked = 1 u
Number of puffs that Mrs Leng baked = 1 u + 461
4 u = 1 u + 461 - 185
4 u - 1 u = 276
3 u = 276
1 u = 276 ÷ 3 = 92
Number of puffs that Hazel baked
= 1 u
= 92
(b)
Number of puffs that Mrs Leng baked
= 1 u + 461
= 92 + 461
= 553
Answer(s): (a) 92; (b) 553
