- How much did Wesley have left in the end?
- Express the amount of money Risa had left as a fraction of the amount of money Wesley had in the end. (Give your answer in the simplest form)

Wesley |
Risa |
| Before |
4 u + 80 |
4 u |
| Change |
- 1 u - 20 |
- 3 u |
| After |
3 u + 60 |
1 u |
25% =
25100 =
14 75% =
75100 =
34Total amount that Wesley and Risa had in the end
= 3 u + 60 + 1 u
= 4 u + 60
4 u + 60 = 372
3 u + 1 u = 372 - 60
4 u = 312
1 u = 312 ÷ 4 = 78
Amount that Wesley had in the end
= 3 u + 60
= 3 x 78 + 60
= 234 + 60
= $294
(b)
Amount that the Risa had in the end
= 1 u
= $78
Fraction of the amount that Risa had left as a fraction of the amount that Wesley had in the end
