1 u + 386 |

- 185 |
| After |
1 u |
1 u + 201 |
(a)
After
Number of croissants that Vanessa had = 1 u
Number of croissants that Mrs Chew had = 4 x 1 u = 4 u
Before
Number of croissants that Vanessa baked = 1 u
Number of croissants that Mrs Chew baked = 1 u + 386
4 u = 1 u + 386 - 185
4 u - 1 u = 201
3 u = 201
1 u = 201 ÷ 3 = 67
Number of croissants that Vanessa baked
= 1 u
= 67
(b)
Number of croissants that Mrs Chew baked
= 1 u + 386
= 67 + 386
= 453
Answer(s): (a) 67; (b) 453
