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

Seth |
Lynn |
| Before |
4 u + 44 |
4 u |
| Change |
- 1 u - 11 |
- 3 u |
| After |
3 u + 33 |
1 u |
25% =
25100 =
14 75% =
75100 =
34Total amount that Seth and Lynn had in the end
= 3 u + 33 + 1 u
= 4 u + 33
4 u + 33 = 357
3 u + 1 u = 357 - 33
4 u = 324
1 u = 324 ÷ 4 = 81
Amount that Seth had in the end
= 3 u + 33
= 3 x 81 + 33
= 243 + 33
= $276
(b)
Amount that the Lynn had in the end
= 1 u
= $81
Fraction of the amount that Lynn had left as a fraction of the amount that Seth had in the end
