- Express the amount of money Wendy had left as a fraction of the amount of money Zane had in the end. (Give your answer in the simplest form)

Wendy |
| Before |
4 u + 100 |
4 u |
| Change |
- 1 u - 25 |
- 3 u |
| After |
3 u + 75 |
1 u |
25% =
25100 =
14 75% =
75100 =
34Total amount that Zane and Wendy had in the end
= 3 u + 75 + 1 u
= 4 u + 75
4 u + 75 = 231
3 u + 1 u = 231 - 75
4 u = 156
1 u = 156 ÷ 4 = 39
Amount that Zane had in the end
= 3 u + 75
= 3 x 39 + 75
= 117 + 75
= $192

Amount that the Wendy had in the end
= 1 u
= $39
