| Before |
1 u |
1 u + 411 |
| Change |

- 131 |
| After |
1 u |
1 u + 280 |
(a)
After
Number of muffins that Jade had = 1 u
Number of muffins that Mrs Chong had = 3 x 1 u = 3 u
Before
Number of muffins that Jade baked = 1 u
Number of muffins that Mrs Chong baked = 1 u + 411
3 u = 1 u + 411 - 131
3 u - 1 u = 280
2 u = 280
1 u = 280 ÷ 2 = 140
Number of muffins that Jade baked
= 1 u
= 140
(b)
Number of muffins that Mrs Chong baked
= 1 u + 411
= 140 + 411
= 551
Answer(s): (a) 140; (b) 551
