| After |
2 u + 35 |
5 u + 5 |
If Diana received another $9 in the end, she would have the same amount of money as Xandra.
5 u + 5 + 9 = 2 u + 35
5 u + 14 = 2 u + 35
5 u - 2 u = 35 - 14
3 u = 21
1 u = 21 ÷ 3 = 7
Amount that the girls had in the end
= 2 u + 35 + 5 u + 5
= 2 u + 5 u + 35 + 5
= 7 u + 40
= 7 x 7 + 40
= $89
Answer(s): $89
