| After |
7 u + 50 |
9 u + 5 |
If Xylia received another $5 in the end, she would have the same amount of money as Jane.
9 u + 5 + 5 = 7 u + 50
9 u + 10 = 7 u + 50
9 u - 7 u = 50 - 10
2 u = 40
1 u = 40 ÷ 2 = 20
Amount that the girls had in the end
= 7 u + 50 + 9 u + 5
= 7 u + 9 u + 50 + 5
= 16 u + 55
= 16 x 20 + 55
= $375
Answer(s): $375
