7 u + 38 |
9 u + 8 |
If Rachel received another $8 in the end, she would have the same amount of money as Eva.
9 u + 8 + 8 = 7 u + 38
9 u + 16 = 7 u + 38
9 u - 7 u = 38 - 16
2 u = 22
1 u = 22 ÷ 2 = 11
Amount that the girls had in the end
= 7 u + 38 + 9 u + 8
= 7 u + 9 u + 38 + 8
= 16 u + 46
= 16 x 11 + 46
= $222
Answer(s): $222
