| After |
1 u |
1 u + 300 |
(a)
After
Number of muffins that Barbara had = 1 u
Number of muffins that Mrs Tay had = 5 x 1 u = 5 u
Before
Number of muffins that Barbara baked = 1 u
Number of muffins that Mrs Tay baked = 1 u + 467
5 u = 1 u + 467 - 167
5 u - 1 u = 300
4 u = 300
1 u = 300 ÷ 4 = 75
Number of muffins that Barbara baked
= 1 u
= 75
(b)
Number of muffins that Mrs Tay baked
= 1 u + 467
= 75 + 467
= 542
Answer(s): (a) 75; (b) 542
