1 u + 442 |

- 127 |
| After |
1 u |
1 u + 315 |
(a)
After
Number of cookies that Jade had = 1 u
Number of cookies that Mrs Sher had = 4 x 1 u = 4 u
Before
Number of cookies that Jade baked = 1 u
Number of cookies that Mrs Sher baked = 1 u + 442
4 u = 1 u + 442 - 127
4 u - 1 u = 315
3 u = 315
1 u = 315 ÷ 3 = 105
Number of cookies that Jade baked
= 1 u
= 105
(b)
Number of cookies that Mrs Sher baked
= 1 u + 442
= 105 + 442
= 547
Answer(s): (a) 105; (b) 547
