Mrs Chew |
| Before |
1 u |
1 u + 321 |
| Change |
|
- 179 |
| After |
1 u |
1 u + 142 |
(a)
After
Number of muffins that Raeann had = 1 u
Number of muffins that Mrs Chew had = 3 x 1 u = 3 u
Before
Number of muffins that Raeann baked = 1 u
Number of muffins that Mrs Chew baked = 1 u + 321
3 u = 1 u + 321 - 179
3 u - 1 u = 142
2 u = 142
1 u = 142 ÷ 2 = 71
Number of muffins that Raeann baked
= 1 u
= 71
(b)
Number of muffins that Mrs Chew baked
= 1 u + 321
= 71 + 321
= 392
Answer(s): (a) 71; (b) 392
