| After |
5 u + 36 |
7 u + 6 |
If Ivory received another $8 in the end, she would have the same amount of money as Xandra.
7 u + 6 + 8 = 5 u + 36
7 u + 14 = 5 u + 36
7 u - 5 u = 36 - 14
2 u = 22
1 u = 22 ÷ 2 = 11
Amount that the girls had in the end
= 5 u + 36 + 7 u + 6
= 5 u + 7 u + 36 + 6
= 12 u + 42
= 12 x 11 + 42
= $174
Answer(s): $174
