- 164 |
| After |
1 u |
1 u + 180 |
(a)
After
Number of muffins that Gillian had = 1 u
Number of muffins that Mrs Leng had = 4 x 1 u = 4 u
Before
Number of muffins that Gillian baked = 1 u
Number of muffins that Mrs Leng baked = 1 u + 344
4 u = 1 u + 344 - 164
4 u - 1 u = 180
3 u = 180
1 u = 180 ÷ 3 = 60
Number of muffins that Gillian baked
= 1 u
= 60
(b)
Number of muffins that Mrs Leng baked
= 1 u + 344
= 60 + 344
= 404
Answer(s): (a) 60; (b) 404
