| After |
9 u + 30 |
11 u + 5 |
If Esther received another $9 in the end, she would have the same amount of money as Tina.
11 u + 5 + 9 = 9 u + 30
11 u + 14 = 9 u + 30
11 u - 9 u = 30 - 14
2 u = 16
1 u = 16 ÷ 2 = 8
Amount that the girls had in the end
= 9 u + 30 + 11 u + 5
= 9 u + 11 u + 30 + 5
= 20 u + 35
= 20 x 8 + 35
= $195
Answer(s): $195
