| After |
5 u + 43 |
8 u + 4 |
If Yoko received another $6 in the end, she would have the same amount of money as Olivia.
8 u + 4 + 6 = 5 u + 43
8 u + 10 = 5 u + 43
8 u - 5 u = 43 - 10
3 u = 33
1 u = 33 ÷ 3 = 11
Amount that the girls had in the end
= 5 u + 43 + 8 u + 4
= 5 u + 8 u + 43 + 4
= 13 u + 47
= 13 x 11 + 47
= $190
Answer(s): $190
