1 u + 356 |

- 184 |
| After |
1 u |
1 u + 172 |
(a)
After
Number of puffs that Shannon had = 1 u
Number of puffs that Mrs Kong had = 5 x 1 u = 5 u
Before
Number of puffs that Shannon baked = 1 u
Number of puffs that Mrs Kong baked = 1 u + 356
5 u = 1 u + 356 - 184
5 u - 1 u = 172
4 u = 172
1 u = 172 ÷ 4 = 43
Number of puffs that Shannon baked
= 1 u
= 43
(b)
Number of puffs that Mrs Kong baked
= 1 u + 356
= 43 + 356
= 399
Answer(s): (a) 43; (b) 399
