| Before |
1 u |
1 u + 408 |
| Change |

- 186 |
| After |
1 u |
1 u + 222 |
(a)
After
Number of wafers that Victoria had = 1 u
Number of wafers that Mrs Chia had = 4 x 1 u = 4 u
Before
Number of wafers that Victoria baked = 1 u
Number of wafers that Mrs Chia baked = 1 u + 408
4 u = 1 u + 408 - 186
4 u - 1 u = 222
3 u = 222
1 u = 222 ÷ 3 = 74
Number of wafers that Victoria baked
= 1 u
= 74
(b)
Number of wafers that Mrs Chia baked
= 1 u + 408
= 74 + 408
= 482
Answer(s): (a) 74; (b) 482
