| Before |
1 u |
1 u + 460 |
| Change |

- 134 |
| After |
1 u |
1 u + 326 |
(a)
After
Number of tarts that Gem had = 1 u
Number of tarts that Mrs Yee had = 3 x 1 u = 3 u
Before
Number of tarts that Gem baked = 1 u
Number of tarts that Mrs Yee baked = 1 u + 460
3 u = 1 u + 460 - 134
3 u - 1 u = 326
2 u = 326
1 u = 326 ÷ 2 = 163
Number of tarts that Gem baked
= 1 u
= 163
(b)
Number of tarts that Mrs Yee baked
= 1 u + 460
= 163 + 460
= 623
Answer(s): (a) 163; (b) 623
