Mrs Loo |
| Before |
1 u |
1 u + 327 |
| Change |
|
- 147 |
| After |
1 u |
1 u + 180 |
(a)
After
Number of cupcakes that Xylia had = 1 u
Number of cupcakes that Mrs Loo had = 5 x 1 u = 5 u
Before
Number of cupcakes that Xylia baked = 1 u
Number of cupcakes that Mrs Loo baked = 1 u + 327
5 u = 1 u + 327 - 147
5 u - 1 u = 180
4 u = 180
1 u = 180 ÷ 4 = 45
Number of cupcakes that Xylia baked
= 1 u
= 45
(b)
Number of cupcakes that Mrs Loo baked
= 1 u + 327
= 45 + 327
= 372
Answer(s): (a) 45; (b) 372
