| After |
6 u + 41 |
11 u + 4 |
If Yoko received another $2 in the end, she would have the same amount of money as Roshel.
11 u + 4 + 2 = 6 u + 41
11 u + 6 = 6 u + 41
11 u - 6 u = 41 - 6
5 u = 35
1 u = 35 ÷ 5 = 7
Amount that the girls had in the end
= 6 u + 41 + 11 u + 4
= 6 u + 11 u + 41 + 4
= 17 u + 45
= 17 x 7 + 45
= $164
Answer(s): $164
