| Before |
1 u |
1 u + 364 |
| Change |

- 162 |
| After |
1 u |
1 u + 202 |
(a)
After
Number of puffs that Tiffany had = 1 u
Number of puffs that Mrs Lim had = 3 x 1 u = 3 u
Before
Number of puffs that Tiffany baked = 1 u
Number of puffs that Mrs Lim baked = 1 u + 364
3 u = 1 u + 364 - 162
3 u - 1 u = 202
2 u = 202
1 u = 202 ÷ 2 = 101
Number of puffs that Tiffany baked
= 1 u
= 101
(b)
Number of puffs that Mrs Lim baked
= 1 u + 364
= 101 + 364
= 465
Answer(s): (a) 101; (b) 465
