| Before |
1 u |
1 u + 368 |
| Change |

- 148 |
| After |
1 u |
1 u + 220 |
(a)
After
Number of cupcakes that Ivory had = 1 u
Number of cupcakes that Mrs Chau had = 5 x 1 u = 5 u
Before
Number of cupcakes that Ivory baked = 1 u
Number of cupcakes that Mrs Chau baked = 1 u + 368
5 u = 1 u + 368 - 148
5 u - 1 u = 220
4 u = 220
1 u = 220 ÷ 4 = 55
Number of cupcakes that Ivory baked
= 1 u
= 55
(b)
Number of cupcakes that Mrs Chau baked
= 1 u + 368
= 55 + 368
= 423
Answer(s): (a) 55; (b) 423
