Gem |
Mrs Chiam |
| Before |
1 u |
1 u + 300 |
| Change |
|
- 174 |
| After |
1 u |
1 u + 126 |
(a)
After
Number of muffins that Gem had = 1 u
Number of muffins that Mrs Chiam had = 3 x 1 u = 3 u
Before
Number of muffins that Gem baked = 1 u
Number of muffins that Mrs Chiam baked = 1 u + 300
3 u = 1 u + 300 - 174
3 u - 1 u = 126
2 u = 126
1 u = 126 ÷ 2 = 63
Number of muffins that Gem baked
= 1 u
= 63
(b)
Number of muffins that Mrs Chiam baked
= 1 u + 300
= 63 + 300
= 363
Answer(s): (a) 63; (b) 363
