Mrs Leow |
| Before |
1 u |
1 u + 327 |
| Change |
|
- 159 |
| After |
1 u |
1 u + 168 |
(a)
After
Number of muffins that Tammy had = 1 u
Number of muffins that Mrs Leow had = 3 x 1 u = 3 u
Before
Number of muffins that Tammy baked = 1 u
Number of muffins that Mrs Leow baked = 1 u + 327
3 u = 1 u + 327 - 159
3 u - 1 u = 168
2 u = 168
1 u = 168 ÷ 2 = 84
Number of muffins that Tammy baked
= 1 u
= 84
(b)
Number of muffins that Mrs Leow baked
= 1 u + 327
= 84 + 327
= 411
Answer(s): (a) 84; (b) 411
