1 u + 425 |

- 149 |
| After |
1 u |
1 u + 276 |
(a)
After
Number of cupcakes that Esther had = 1 u
Number of cupcakes that Mrs Loh had = 5 x 1 u = 5 u
Before
Number of cupcakes that Esther baked = 1 u
Number of cupcakes that Mrs Loh baked = 1 u + 425
5 u = 1 u + 425 - 149
5 u - 1 u = 276
4 u = 276
1 u = 276 ÷ 4 = 69
Number of cupcakes that Esther baked
= 1 u
= 69
(b)
Number of cupcakes that Mrs Loh baked
= 1 u + 425
= 69 + 425
= 494
Answer(s): (a) 69; (b) 494
