+ 40 |
+ 8 |
| After |
3 u + 40 |
5 u + 8 |
If Yen received another $4 in the end, she would have the same amount of money as Ivory.
5 u + 8 + 4 = 3 u + 40
5 u + 12 = 3 u + 40
5 u - 3 u = 40 - 12
2 u = 28
1 u = 28 ÷ 2 = 14
Amount that the girls had in the end
= 3 u + 40 + 5 u + 8
= 3 u + 5 u + 40 + 8
= 8 u + 48
= 8 x 14 + 48
= $160
Answer(s): $160
