| After |
1 u |
1 u + 351 |
(a)
After
Number of tarts that Gabby had = 1 u
Number of tarts that Mrs Chye had = 4 x 1 u = 4 u
Before
Number of tarts that Gabby baked = 1 u
Number of tarts that Mrs Chye baked = 1 u + 494
4 u = 1 u + 494 - 143
4 u - 1 u = 351
3 u = 351
1 u = 351 ÷ 3 = 117
Number of tarts that Gabby baked
= 1 u
= 117
(b)
Number of tarts that Mrs Chye baked
= 1 u + 494
= 117 + 494
= 611
Answer(s): (a) 117; (b) 611
