| Before |
4 u + 40 |
4 u |
| Change |
- 1 u - 10 |
- 3 u |
| After |
3 u + 30 |
1 u |
25% =
25100 =
14 75% =
75100 =
34Total amount that Mark and Linda had in the end
= 3 u + 30 + 1 u
= 4 u + 30
4 u + 30 = 290
3 u + 1 u = 290 - 30
4 u = 260
1 u = 260 ÷ 4 = 65
Amount that Mark had in the end
= 3 u + 30
= 3 x 65 + 30
= 195 + 30
= $225
(b)
Amount that the Linda had in the end
= 1 u
= $65
Fraction of the amount that Linda had left as a fraction of the amount that Mark had in the end
